Comment 10 for bug 644066

I can do the mechanical steps of submitting the screenshot images for upload, if you create the images. We'll need two PNG files of the screenshot: a full-sized one and a thumbnail. The recommended size for these is 800 x 600 and 160 x 120, though there's room for variation.

The icon for the application is already handled in the .desktop file, so you don't need to do anything there.
