HTML Wrapper creates html wrappers, or in other words an html coded page that contains 1 image centered. You can configure the number of wrappers to be created, as well as the background image and the background colour of the html file. This is useful if you run a site that has pictures and you want the image to be a) centered and b) the only thing on the page. A lot of XXX hosts require you to have your images in "wrappers".. this will deter people from hot linking to your images
