How can you create a paypal button into a gallery page ??

I have a gallery setup on my site that I created using firefox and it has thumbnails.. once you click a thumbnail it enlarges a photograph. Does anyone know how to place the paypal button underneath each enlarged photograph under the caption for that photograph? I tried just placing it next to the caption with no luck. www.cliftondesigns.com to see what I am talking about.. the photography pages is what I would be doing. also I noticed that when you view the source for the page it only shows the main pages source... it doesnt show you the slideshow page that was created when I created the gallery that has the slideshow code. (gallery created in firefox) Here is some of the coding on the slideshow page.. I am not sure where to place or how to place the paypal button and if I need to add any more code to make it work. .... each line item has a photograph caption name so each of them would have its own paypal button.
