Purchased a Wordpress Theme, just have two problems left to sort. Gallery photos display properly on the page, but when I click any one photo, it loads as a separate blank web page, it's supposed to load as a slider on top of my existing page. According to Theme documentation I am to ask:

"ensure your hosting provider supports by GD Image and Timthumb"

So, does it?
I have resolved all other documentation suggestions. Any help appreciated.
