210462 Help with Simple Image Gallery

I have the new pro Simple Image Gallery version. Thumbnails are OK, but when you click on an image and the litebox pops up the image is the same size as the thumbnail. Here is an example of what I am experiening but do not know how to over come: [login to view URL];task=view&id=12&Itemid=26 Thumbnails are at the bottom of the page. I have also noticed that when I try to increase the size of the thumbnail on the page that it will only show one image and not the rest of them, but If I make the image small enough I can view all of the thumbnail images. So this is a two part project. 1. I need to increase the size of the thumbnail as large as posible to allow for 3 thumbnails across. 2. When a person clicks on a thumbnail and the light box pops up I want the picture to fill at least 3/4 of the page. Please check the link above in order to fully understand what I am wanting. Simple Image Galley Pro is a paid subscription. Thanks and Happy Bidding!
