Let me qualify this comment by saying I have no clue about Photoshop, but I do remember that there is an remark on the upload page about a problem with photoshop. In one of its modes, it makes an automatic thumbnail. R'osity apparently cannot cope with that, and the warning states that it must be disabled. If that is the problem, simply take your image to Photoshop and resize it to 200 x 200 or smaller and export it as a jpg with the quality necessary to make it under 15k, save it with an name. I usually save my large image with a name (image.jpg) and my thumb with a similar one (imageth.jpg) so that they will be next to each other on my R'osity upload list. Hope that helps. Tres
