As the name implies, a Single Thumbnail Gallery only shows one thumbnail. To view the rest of the image in the gallery, your visitors would need to click on the thumbnail. This will open the full size image in FooBox, or another lightbox (if installed). Here’s an example.
With this gallery, you can adjust the size of the thumbnail. You can also change the position of the gallery on the page. It can be center, left or right. Alternatively you can float it left or right, meaning that text will appear next to the gallery.
You are also able to set the images to open in a lightbox, such as FooBox.
