Well, here;s one way to do it:
Submitting an Image
To submit an image to a category, visit the category you wish to submit your image to, and click on 'New Image'. If the administrator allows you to bulk upload images, click 'Bulk Upload'.
Similarly, to submit an image to one of your own albums, you can visit your album in the Gallery and click on 'New Image'. You can also go to 'My Controls' and select 'Upload Image' from the drop down next to any of your albums.
