pedalpete: We all may know what a slideshow is and looks like, but how about a demo of what YOUR slideshow looks like? Does it make sense to describe your product using your product (have a slideshow that guides me to how to use it)?Also, for a site that deals with slideshows and images, I would expect more care to be put into the design. 
Your logo is very pixelated, you have a square color behind your buttons, etc.These may seem like minor things, but I think you'd be amazed at what some care in design can do in attracting users.You don't have to go out and get a designer and spend lots of money, but maybe get a theme from themeforest (under $20) or try to find something free.
