be recreated, so junking those isn't an issue. But stripping unrecoverable information, especially that which may contain author and license information, is a problem when the images are borrowed and used downstream. I wish I had a good way to strip just thumbnails, but I don't currently know of one. Flickr has the same practice as well, and it's annoying....
There has been some recent discussion on what exif data we should include in thumbnails. It is for us technically possible and generally people think it is a good idea. Unfortunately, some cameras add 25 KB of exif data to a picture; which is about the size of a thumbnail itself. The exif data has to be stripped before attached to the thumbnail.
I realize that I'm not a part of your community and that I'm injecting an outside viewpoint. And, as a third party, there's only so much I can do. But I'm more than happy to discuss these issues if it is helpful.
Outside views are greatly appreciated. As a Wikimedian you see things troubled; whether you want to or not. I'm very glad that you have taken the step to the mailing list.
