I have just uploaded a few jpeg illustrations via FTP and they are ready to submit.

I can't see any button or option that will send them into jpeg illustrations category. Am I missing something? Maybe they are categorized automatically using keywords? Or during the review process?

When you enter the title and description, there are 2 checkboxes below the description field� one for photo and one for illustration.

Oh thanks, I didn't notice that thing, as the images already had IPTC data. I did look at the keywords but not the description.
