Not sure why you have PR0 after being online for over 9 months, and with Yahoo reporting over 600 backlinks. You are indexed by Google, so they know you exist. The likely problem is that your site is in the Sandbox. Plan on being there for awhile.
Dominique is right, add more content to the site. Search engines don’t care about images, they only read content, and the more you have, the more traffic your site will generate. Even while you are in the sandbox, you can get traffic for non-competitive search terms.
