Ok, i've done almost everything, but i had some problems:

- I really need to dont allow users to send images to the main category but only to the sub-category, how?

- I want to add a text above the "Category" select box on "Send Image" where can i do that?

- And I dont understand the super delete? How do i allow users to delete only their own images?

- In admin, on the section i have to approve images, its possible to appear the image? so i can approve or not if the image is in the correct categoru...

Hope you understand me, and big thanks by the help :)
