Large pictures in product info.

[bfbcacid]

Hello,

I'm new to to the site and wanted to say thanks to all who post here your info has saved me weeks of trouble shooting.

 

I have one request and I have been searching forever. I have two picture types one small and one large they all work great. A thumb sized is shown when people click categories and then when they click the product again it displays a thumb sized one and if they click on the photo it shows the large popwindow picture. Here is what I am trying to do I want to display the small one when people click the categories and when they click the item I want the large photo centered and under the description. Is this possible. Any help would be greatly appriciated.

 

BTW: I am running BTS

 

Thanks in advance
