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.
