There are options to enable it for all links pointing to an image on your site (with option to exclude some pages), or just on selected pages. It can be enabled only for image links with CSS class=”shutter” with option to create a single set or multiple sets for each page.
The plugin can also “auto-make” image sets for each Post, so when several posts are displayed on the “Home” page, links to images on each post will be in a separate set. See the built-in help for more information.
