My professor once said something to the effect of "You sell something for free when you're combating the anxiety of loss. You don't go free to compete on price." I guess one thing you have to ask yourself is if your customers aren't coming because they're afraid of losing something, even with the 7 day free trial. I don't necessarily think you need a free version. Also, it's easy to decrease prices but difficult to go up. I agree with some of the other posts that suggest you should add some more illustrations of what the product does. Sitting in my armchair I don't see the difference between this and a flickr album besides being able to post 4 pictures side by side. I'm not your target audience though so I don't know what problems your customer segment has.
