There's been some inquiries recently about images submitted to the wrong categories. It makes things easier on me and the admins if you make sure to select the right one when submitting. Btw the "Others" folder is only for things that aren't covered by the previous ones, such as flash animations or statues.
However, if you do submit to the wrong category, there is no need to let us know or to delete it. It will still be accepted, and it will be moved to the right place after a while.
