I have a few Abstract Smoke shots I want to upload but I cant figure out what categories to put them in. I tried looking up other shots on there but they dont show the categories they are in. Any Ideas?

"art abstract" and 'arts background' (if the latter would be appropriate). Don't sweat it. Rumour is that categories aren't used much., and in fact, I can't see much benefit of anyone using them. In fact, some 'search by category' categories aren't even categories we can enter (!) F'r instance, I just went into 'advanced search' and clicked on 'search by categories'. I then clicked location and drilled down through Africa (there is no Africa category we can enter)> Southern Africa> Botswana >Savuti > Savuti Channel - and got a search result exactly the same as if I'd done a regular search on Savuti Channel. So why would anyone bother?
