This module is easy to install, easy to configure, is centering itself in the side rail, has a nice transition, and pulls images from the file I specify. That's everything I was looking for (and I haven't been able to find all of those things anywhere else).
You can select whether to pull photos from a file or to select only specific photos. That's a nice plus.
Except... I don't see any way to center it in the sidebar where I have it positioned. And you can only add 10 photos. Ideally, I'd like to just point the module toward a specific image folder and have it rotate between the images in the folder.
Not pulling from a folder isn't a deal killer for me. Not being able to center the module is, however. The module looks sloppy when it's too far to the right. If that gets fixed, I'll gladly change my rating from Good to Excellent.
You can upload N number of images into the images folder. In the admin we have option to set the image folder.
No admin option to change the image position. But you can change the DIV class in the module JS file.
