Are you able to make a picture/classified like website with Squarespace?

I have idea for a niche specific picture/classified base website or something along those lines and want to find out if I was able to do something like this with Squarespace? If so, what are the steps I need to take in to take.

Just start your risk-free (no credit card required) free trial with Squarespace. You get 14 days to try out building your website. If you like what you have at the end of your trial period, just become a paid customer or else you can throw your work away from the trial period. http://www.squarespace.com/templates/
