I have some problem using very simple image gallery plugin for joomla 1.5.It takes long time to load images when click on the thumbnail images.I have enabled the use javascript features.
How can I reduce the loading time of the big images when click on the thumbnail images?I have to enabled the "use javascript" option as that is the requirement.
hope this link will help you:

Use this Photo Gallery Plugin which is very effective,
on the other hand you talked about to reduce the loading time, i don't know if that possible but
if you can reduce the size of the image then it will take less time in loading.
if you know a little bit about photoshop the is easy to follow these steps:
Open the Image
Resize According to you to press Ctrl + t button
After resizing press Alt+Ctrl+Shift+ s
A Window appear and the right side you got the options to manupulate the image in different format like .jpg, .gif etc.
Choose .jpg and set the value 60 in 'Quality' box instead of 100.

I am using Fancybox. In a slideshow where the thumbnails are not reduced from larger images, and are linked to separate full-size images (that will appear in the slideshow when thumbnails are clicked), will the full-size images also pre-load with the webpage? Or only load when the slideshow is activated? My slideshows have many images, and I don't want them to load until necessary. Thanks in advance for advice!
First, you can use developer tools to easily check network activity.
The script fully loads current and previous/next slides after it is activated. Thumbnails are, hoverer, all loaded at once. This means, that if you have extremely large quantities of images, the script will load only max 3 of them and it would be better to disable thumbnails.
I am using the facebook plugin on my wordpress website. My posts are image-only. I am able get the open graph functionality to work, however the image is either a tiny thumbnail with a useless excerpt box beside it, or full-sized with half of it cut of because of the useless caption box.
Now, I say useless, but I wouldn't mind having only my url presented below the image if possible, but without all the extra space. It looks terrible. Also, My image posts do not have titles so in the excerpts box the only title option without a separator for the "collection" theme I am using is sitenameonly....which leave my
sitename
site url
< .........huge extra excerpt space..............................................................................................................................................................................................................................................................................................................................................................>
I have looked elsewhere, in fact all over but can't find information to:
make images full-sized (as if they were posted directly to facebook)
Remove extra space in the excerpt box, leaving only the url
(or remove the box entirely--leaving a full-sized image)
thanks so much in advance
As long as your Wordpress plugin assigns a proper image to each post using the og:image tag and the conditions stated below (emphasis added) then you should be able to get full size posts.
We've increased the size of images in link page posts by 4x on mobile
and 8x on desktop to help you drive better fan engagement. As part of
this change, we've also made the aspect ratios for images consistent
across mobile and desktop. We recommend the following steps to
optimize your images for this new format:
Use images that are 1200 x 630px or greater for the best display on high-resolution devices. At the minimum you should use images that are
600 x 315px to display link page posts with larger images.
Use images that have an aspect ratio of 1.91:1. Try to keep your images as close to this aspect ratio as possible to avoid any cropping
in News Feed.
Use the og:image tag to choose the image that you want to share. If you don't use the og:image tag, users can choose the image they want
to post, giving them a chance to select an image that is poor quality.

I have a bunch (about 20)thumbnail jpg images that I want to enlarge to a much bigger image when you click on each thumbnail. But I dont want to have so many large jpgs on my website, because that will slow down the entire site.
Whats the best way to enable the user to view the thumbnail in large without making them into big jpg images?
I need the enlarged image to be as big as possible, because each one has text that I want the user to be able to read easily.
The link to my site is www.totalrecallsolutions.com
I dont want to make them into pdf's because not everyone has a pdf viewer, and I dont want to make them download it.
I also dont want to code each image onto its own webpage, even though I know that that will be able to be as big as I want, because I dont want to spend all that much time.
Any other options?
Thanks!

I'm a little confused. You don't want to host the images, or you don't want them embedded? If you don't want to host them, use something like photobucket. If you don't want them directly embbeded to your page, look at javascript popup windows.
On some occassion, Google Chrome download a line (of maybe 20px) at a time and display it right away. So the picture is rendered from top to bottom. Using html tag results in this.
On other occasion, Google Chrome displays a picture from facebook photos in an interleaving way, first a bit grainy, and then it becomes clearer as more data has been downloaded.
This way the picture is displayed wholly at first with low resolution and the resolution is getting higher as if it's being streamed.
Is there a special tag to do this "streaming" ?
The correct word is "interlace" - when you save the image in some web formats (.jpeg for example), you often have the option to save it interlaced - I know this option exists in Photoshop's "Save for Web".
So it's not an html tag - it's the way the image is encoded. And then the browser has to be capable of "streaming" interlaced images (most modern ones are).
Hope this helps
We're using the facebook graph API http://developers.facebook.com/docs/reference/api/post/ and adding the picture parameter. Our picture is a 30x30 pixel image, which is exactly the size we want for the facebook web version. However, the image will be pixelated when using the FB mobile app on an iPhone4 (retina display).
Is there any way to serve a 60x60 high resolution image, but render it always at 30x30 for facebook wall posts?
Well.. as of this moment, here is what I have found out, and offer a 'solution' that has worked for me based on the time i've had to test & play with this concept. For all the readers out there, who need a quick answer to the question, i don't have the exact solution to the question, but…. Essentially, your 30x30 image is being scaled to 90x90. The 60x60 image is being scaled to 90x90. And I can not find a way to go around this.
Below is what I have tried. Feel free to add input.
Take your feed image, and stroke a 2-5px black line around the frame of the image.
Load up your app, initiate a wall feed on the device. With the image present, take a screenshot. Mail yourself the image. Open it up in Photoshop (or photo editing program). Use a Marquee tool to outline the image. Cut it out of the screenshot and paste it as a new image. What size is it? 90x90, right? (and obviously 180x180 if image is retina)
Create a 90x 90 image. Copy your original 30x30 image and paste it anywhere you want within the new 90x90 images' frame. Upload it to the URL parameter's location. Re-run your app. By re-running it, i mean you have to shut it down completely, it appears as though the SDK is cacheing the image upon first launch of the feed and you can clear that cache by closing the app completely, and rerunning it. When you do, you will see significant improvements with the look of the image. It may not be a retina image, but it at least won't be 'fuzzy ugly'. At this point, it boils down to how nice of illustrative lines that where done in the design process to remove the aliasing effect produced from the conversion to a raster graphic. As well, i'm not sure if a variation of resampling method will produce even better results.
Some things i've tried:
I've also saved it as a png file with no transparency : 144ppi at 90 x 90 size. In other words, save your 90x90 image with a higher resolution (pixels per inch). Remember to not constrain proportions as you image resize. And note that If you are using adobe products, i.e. photoshop ) - don't save for web, just use 'save as…', as this will retain the ppi you specified. Although, i don't believe i see much of a difference in the quality which this is displayed going this route, and best to try to keep the file size down as this will increase the overall image size by about 500% or more.
I've tried variations of hosting the image twice the size (180x180) within the same hosted folder and naming it image#2x.png & image-large.png <--(just for the heck of it). This is not really solving the problem either.
Some other things I have not tried:
Monitoring your web server traffic, and any "not found" errors to a resource to see if FB is trying to access an a potential alternate resource when grabbing your image for display, the wall feed box that comes up is a webview. Meaning web graphics. (It's FB's web page…meaning their rules, and i doubt the pages' source is available to dabble with within the SDK.. so!…
Look at the HTML of the feed itself with safari browser:
The inspection of the HTML within the final resulting image that is posted on my FB wall I can see this….
<img class="img" src="http://platform.ak.fbcdn.net/www/app_full_proxy.php?app=153675474666495&v=1&size=z&cksum=773bba91f6146b2463eed0a0bb77dc42&src=http%3A%2F%2Fwww.thumbwizards.com%2Fspeakinapps%2Fgraphics%2Fboxed%2Faussie.png" alt="">
I am wondering:
Within HTML5 isn't there a mechanism to provide a toolkit type of javascript to display retina graphics from a web page?
Would it be possible to have that code run when grabbing the url to the image (in meaning, the url of the image would be acting as a pointer to the code.? I haven't tried playing with this, since my logic tells me that per the url above that FB is essentially taking control over the image at this point. I have noticed (and not waited long enough to see) that the image is apparently cached and posting to the wall with a new image, sometimes results in the older image still being used. (and yes, i've cleared my browser cache)… perhaps simply cached in another location..
If there is another parameter for the image type, that is not published, I have not stumbled across any yet.
Can anyone figure out if through source of:
[http://platform.ak.fbcdn.net/www/app_full_proxy.php] if this php file is part of an available image processor out there we can access to view what could be done?
Can anyone mention an app that uses a retina graphic in their feed post?
Just thoughts really, I've decided to not really give a crop, and if
you've made it this far. Thanks for tuning in. ..So, Sulf, your 30x30 is being scaled to 90x90. making it UGLY!.
Good luck.. If you figure anything else out, let me know!

apple specify that if you want to add the retina effect for your ios app then the images you are using in this format -i.e
sampleImag.png- 57*57(size) , 163 (DPI)
sampleImag#2x.png - 114*114(size),326 (DPI) when you use these specific graphic images you will get your app is showing retina effect in iphone 4 and above generation.
Just point your code to a larger scaled image and Facebook will take care of the rest.
