2 questions: button and displaying the button

Hi guys,

Just downloaded and installed the plugin. It looks great and is displaying the Buy now text under each product.
However i cant seem to make that text look like an actual button. Can you help me out here?

Also, i have some pics at a few pages, which must have the Buy now button under them as well. I cant really figure out the code to use here, and where to place it so that the button eppears under the pics.

Hope you can help.

Cheers!
