dynamic media and scene-7 integration in AEM - aem

Can someone please give insight about Dynamic media and Scene 7 integration in AEM? I would like to understand why we integrate Dynamic Media/Scene-7? Difference between both.
I am not able to find many articles on Scene-7/Dynamic media online.
I would like to understand why we append "/is/image" for .jpg, .png, etc. images and "/is/content" for .gif images in the URL?
Thanks in advance!

Umbraco 8 - Upload and Embed Videos from Local File

What I'm trying to achieve is to upload a video to the Media section in Umbraco 8 CMS and embed then choose the video to embed in Content, just like what is normally done with images. The video can be .mp4/.avi etc.
Looks like Umbraco 8 only supports YouTube and Vimeo videos, but that's not ideal in my case.
Umbraco 8 supports a lot more than YouTube and Vimeo out of the box: https://our.umbraco.com/apidocs/v8/csharp/api/Umbraco.Web.Media.EmbedProviders.html
If there IS an external provider you'd like to use, but it isn't in the list above, it's possible to create your own embed provider to make the Embed dialog support it. As long as it supports OEmbed it shouldn't be crazy complicated to do, I think. Have a look here: https://our.umbraco.com/documentation/extending/Embedded-Media-Provider/
In case you are simply not able to use an external video service, you probably have to do something like what is mentioned here: https://our.umbraco.com/forum/using-umbraco-and-getting-started/84626-inserting-video-banners-in-umbraco (in short, create a Media Picker property on your document type and handle it in the template like Micha describes)
In umbracoSettings.config file there's a section disallowedUploadFiles. Is Mp4 in there? You should be able to do this
There is also a max file size, so maybe check your vide is under that as well

Optimise images in AEM

We are using AEM 6.2 and want to optimise multiple images in AEM to get a low resolution image. Please suggest how can we get low resolution images upon uploading the images or some other way.
If you are using ACS commons, explore named-image-transform else you have to generate custom renditions using Workflows.
If you already have an Dynamic media add on , try to leverage smart imaging
You can leverage ImageMagick and modify the DAM Asset Workflow to create low-resolution images renditions.

NITF uses the eXtensible Markup Language(xml) to define the content and structure of news articles.

Use NSXmlParser to parse the data.. Then display the content accordingly..

iPhone: random "image of the day" type service?

The iPhone makes it really simple to snarf down an image from the web; you can turn a URL into a UIImage in one line of code. So I'd like to enable my app (an educational puzzle game... my first!) to download some random images to make it more interesting and dynamic.
I thought about using Kodak's image of the day RSS feed, but I'm having quite a time figuring out how to parse it. Rather than being a simple list of image URLs, it seems to reference a bunch of "jhtml" URLs, which run Javascript to display the images in your RSS reader. Is this intentionally obfuscated, or am I missing some basic step to parse this?
I also tried the Astronomy Picture of the Day, via this RSS feed, but it's just the original page's HTML stuffed into CDATA... ugh.
So I guess this is really two questions:
Is there a simple way to parse these feeds to actually get at the JPG URLs on the iPhone?
Is there a better source for "picture of the day" type images?
PS: I'm using NSXMLParser, which I learned to use here.
I would recommend going with something that has an API, perhaps the Flickr "Interestingness" feed:

There is an objective-C library written to help with accessing Flickr but not sure if this API call is included:
