It works!!
I've been using the built-in image gallery feature of my website for attaching images to posts -- log entries, web pages, events, etc -- which meant redundancy in the design.
Now, you can grab a picture from your Cheddarmonger album and insert it into your postings! That means that you don't need to upload extraneous pictures anymore.
When creating a new page, simply hit the "add Gallery2 images" link in order to browse your album and insert a picture!
Sounds like a nice feature. I need to go over and check that out.
