P.S. This is not untrue for software in many cases. Some products get a big boost out of screenshots. Many don't, and instead get big boosts by e.g. showing pictures of users or the team which wrote the software. (Whether a screenshot helps is surprisingly uncorrelated with my subjective impression of which products are "pretty", even given that I have less artistic sense than a mole rat.)
Any tips btw. for content I should have on the site for SEO purposes? Even though I rank for the generic term "japanese candy" and also some specific candies, I haven't been able to convert people except those searching for the site specifically (http://i.imgur.com/OnVIF.png)
