I recently started my own image hosting site. Users are allowed to add title, descriptions and links (dofollow) to each image they upload. Pages are SEO friendly. For everybody: What do you thing about this site. For experienced: Can this site be useful to the users that need backlinks? Share images and get backlinks
I would try to make the site a little more exciting.. a bit more web 2.0 styley maybe add some images or diagram of what happens post picture>create your own description and link>get backlink wether its viable for backlinks depends on it getting a high page rank before people consider it as viable but might be used if it was easy to upload e.g through a app or bulk upload... but you may get spammed to hell to
The site is friendly and simple but I suggest you get more traffic to hype off your site because it has more potential.
