Typically through search engines SEO and free social sites where you display some samples, Facebook allows separate Business pages for any legit business, Pinterest is a graphic oriented sharing site with a strong female demographic.

Here's a Search Engine Optimization guide by an SEO authority, too much of the stuff taught by others is out of date or simply inaccurate.

Paid advertising would probably not be cost effective, there are photo broker sites that might get you like $1 per user licencing photos for their web sites.
