Facebook ui share method displays small thumbs when shared from mobile - facebook

I'm using FB.ui share method to share links on Facebook.I have to use this method since I want to tag friends on my post.
window.open(
'https://www.facebook.com/v2.1/dialog/share?app_id=&display=popup&redirect_uri='+encodeURIComponent(REDIRECT_URL)+'url='+encodeURIComponent(SHARE_LINK),
'facebook-share-dialog',
'width=750,height=393');
Even though my og:image has the right size, i.e 1200x630px when shared on Facebook the shared link is displayed with small thumb.
When I change the method to FEED dialog or SHARE using facebook/...//sharer.php URL large thumb is shown for the shared link on Facebook.
window.open(
'https://www.facebook.com/v2.2/dialog/feed?app_id=&display=popup&redirect_uri='+encodeURIComponent(REDIRECT_URL)+'&link='+encodeURIComponent(''),
'facebook-share-dialog',
'width=750,height=393');
return false;"
IS there any additional parameter that I need to add TO https://www.facebook.com/v2.1/dialog/share so my image is displayed correctly I.E with large thumb on Facebook?
Thanks.

I had the exactly same issue. I was using "/sharer/sharer" for sharing links and everything was working well. And when I try to use the "/v2.1//dialog/share" I noticed that on desktop, images are big (1200 width) but on mobile (web and iOS App), the share is displayed as a small square.
I think it is because when you use "/v2.1/dialog/share", Facebook assume you share a story through your Facebook App and on mobile UI, story are displayed with small square image :-(
When you use the /sharer/sharer, there is no association with your app and Facebook will just assume user share a link in his feed. And it is the only type of share that display large image on all platform (desktop, mobile and iOS app)
So basically I don't think you can force FB to display large image :-(.
The Facebook doc say that providing big image will result in big image display but it looks like it is only the case for desktop. And for mobile only link status are displayed as big image.

Facebook Tab App Sharing issue with Image

I'm having issues when a user tries to share the URL to a Facebook tab app that I have setup.
When they paste the URL to the tab in their share window and then post their status update, the tab image is shown when viewed on their profile, however there is no image shown on the newsfeed version of the same post.
I've tried adding open graph meta tags to the app, but I believe that it is being ignored since it is located inside of the iframe, and the facebook open graph meta overrides it.
Does anyone know how to ensure an image is maintained when the tab URL is shared directly?
I've burnt a lot of time trying to solve this issue as well. The best I've come up with is that Facebook is going to chose to display the 111x74 app icon. Sharing this on a page's news feed makes it very pixelated and oddly offset, as it should be using a 1200x630 minimum image size, as dictated by the OG tag best practices, but Facebook has not allowed us to have that option in the app configs. It may be that your app icon is being offset enough to not appear like it's visible in the news feed.
So, from my research, we're out of luck until Facebook decides to fix this issue. Until that time, I don't think it's even worth trying to get the any image to work.
Someone feel free to prove me wrong.

why does facebook's thumbnail cache use wrong image and debugger shows correct image?

i have written a plugin for the elgg social networking platform which supports sharing links to other social networks.
mostly this is ok.
i am noticing though that facebook often shows incorrect images for the video thumbnails and other sites, such as google+ are ok.
the url i am passing in to the sharer page is correct and when i use the facebook debugging tool, i see the correct image - e.g. https://developers.facebook.com/tools/debug/og/object?q=https%3A%2F%2Fwww.infiniteeureka.com%2Fvideos%2Fwatch%2F6980%2Fwater-as-primary-healing-agent-dis-ease-is-commonly-due-to-dehydration
as an example - this is the url that the plugin currently outputs for facebook, when sharing a video on my site:
https://www.facebook.com/sharer/sharer.php?s=100&p[title]=water+as+primary+healing+agent+-+dis-ease+is+commonly+due+to+dehydration&p[summary]=description&p[url]=https://www.infiniteeureka.com/videos/watch/6980/water-as-primary-healing-agent-dis-ease-is-commonly-due-to-dehydration&p[images][0]=https%3A%2F%2Fwww.infiniteeureka.com%2Fmod%2Fvideolist%2Fthumbnail.php%3Fjoindate%3D1293022025%26guid%3D6980%26owner_guid%3D2%26size%3Dlarge
when i share this to facebook, i see a thumbnail for another video which i shared days earlier, which has a different url. (edit: i now notice that i can choose from 3 images in facebook and one of them is the correct one - so facebook is building an array of 2 incorrect images in some way and is defaulting to an incorrect one.)
anyone know?
I run into this problem often as well. Try to make your image around 1080px # 1080px and see if that helps. The other options is to try and lazy load all the other images so facebook doesn't pick them up as I presume the thumbnail you are referring to is on the page?

How to post a large image to user's Facebook timeline

I am building a site that lets users browse 3d images. I have added a facebook share button. That button works, but it shares the URL and only a small thumbnail (the thumbnail only works sometimes).
Is it possible to create a button that shares a large custom image, in the same way that you upload a photo to your own timeline?
I cannot use meta tags, because the images change through javascript.
I also cannot let facebook find the image automatically, because it is rendered in a canvas 3d viewer on the webpage.
Thanks in advance!

Use the favicon at the news box at timeline

Why the apps just have the option to configurate one icon (16x16) to show at the users timeline? What about be possible to use the page favicon?
I work at a big media company and we have some diferents produts under our website. We wanted to show the page favicon at the users timeline to differentiate which product the user had visited.
The icon Christian is talking about is an app icon on timeline. Not the image of the url. At this point is not possible to customize this icon by url. I work for a great portal with a lot of different trademarks. We are being forced to make an app for each one because of this issue.
Facebook says the image must be at least 50x50 and no greater than 3.0:1 width:height aspect ratio. So a 16x16 favicon will be ignored when making the post (although due to bad programming on the linter tool likes 16x16 images and tells you that it's just fine).

How to replicate facebook photo view and show photos very fast from web

I have to create same functionality as facebook has does like all the photos display at one view and from that user can choose photo and it goes to large photo. This photos are showing very fast. I have 5 photos from web but it take so much time. Does anyone know how they shows photo very fast.
I don't know the answer but I suggest you look at the three20 source code on github. Joe Hewitt (who wrote the Facebook app) published much of its code including the photo view. There is also a Google group that discusses three20.
I don't know about the iphone app in particular, but I do know that the main facebook website prefetches images in photo albums.
Facebook creates multiple sizes of each photo when it is uploaded. They also convert all the photos to png I'm pretty sure, likely reducing the file size of the original photo. I know creative has often complained about the "quality" of photos after uploaded to Facebook.
This allows them to deliver the appropriate sized image (both dimensions and file size) for quick display rather than delivering a full sized image and having the client resize it.
