Chameleon’s “Enhanced Picture” is a wonderful feature that allows for a more pleasing album look. It allows one picture to be displayed in large size for each folder, and is well documented in the Help.
The recent addition of a comment with the Enhanced Picture enables more artistic freedom; this tutorial presents a few interesting uses related to “hidden folders“. See the tutorial Hidden or Private Folders. The Enhanced Picture comment can be used as an effective “Folder Link” to part of an album that is (but does not have to be) excluded or hidden.
