Imgur is solving this by creating a "community" with comments and up/downvotes, so that user have incentives to open the full page and browse it (this is, by the way, one of the reasons why I don't like imgur at all). They also offer albums, which can obviously be seen only from the full page. OP should look into adding things like that, some contents to encourage users to link/look at the whole page, and not only at the image.
