img: Fix adding of dependency from page to the image.

This was impressively broken. add_depends was being called with params
backwards, and on parameter was set to the name of the generated
file, which isn't in the source.

Now updates to images will update the page that contains them, thus
updating them. This is unncessary for fullsize images, so skipped.
