Very Good

This plugin is lightweight, simple, and works very well. However, it would be better if it were more obvious to the visitor how to close out of the photo gallery. There’s a small “X” in the upper left corner, but most people expect to see that in the upper right.

It would be yet better if the plugin allowed you to include a label, such as “Return to Gallery Page” or “Close Window”. Those things are not as obvious to site visitors as one might think.
