Every time I go to upload an updated background image at Encyclopedia SpongeBobia, it automatically adds "png" to the end and doesn't replace the old image:

This: http://spongebob.wikia.com/wiki/File:Wiki-background.png

Should be here: http://spongebob.wikia.com/wiki/File:Wiki-background

Thanks for any help.
