Flickr and DeviantART are really the only ones that get big views.
Flickr is good or a tumblr I suppse
its hard it really is. put your stuff into local art shows and be known locally, being known locally and as a person is better then a name and a profile on the internet. tell people to spread your name, even make buissness cards and hand them out
Are the photos of people?

as i'm a photographer i prefer flickr. a great way to learn with creative comment
