The form, to the right, runs a cgi that instantiates Modules::concentricPreviewGallery. It is here so people can try out different options, and see what the tables look like. A couple of notes about the demo.

1. The Center Image Height, and Center Image Width options, do what they suggest. They determine the height, and width, of the center image.

The module itself will accept any integer value for height, and width, and is not limited to the values in the selection boxes.

2. The Thumbnail Size Percentage option defines the height, and width, of the thumbnails around the center image, as a percentage of the center image's dimensions.

Try selecting different values for Thumbnail Size Percentage to see what effect it has on the tables.
