Wonderful module. I've been struggling for a week with creating node images, node galleries, organic group galleries and user galleries without using multiple modules and requiring different upload methods for each (very tacky in regards to user interface). With a little help from views and some custom content types your module does it all. Because of all the ways I'm using it, which makes it extremely powerful, I have a few feature requests (I will submit each one seperately). Unfortunately, my php coding is pretty weak, but I would be glad to test or write documentation.

Firstly, it would be nice to be able to set the image format in node body to a custom size, or something other than thumbnails or full size image. I could change the thumbnail size to be 200px or 250px but then the gallery page doesn't look right. I would think most people would want a larger size in the node when only including one or two images. This option would eliminate my need for the tinymce image assist module since the user could just weight one or two images to be in the node and I can theme them were I want them.

Also I will add my vote to rolling http://drupal.org/node/135572 (altering the image gallery layout) into the module. Although I would like one line of thumbnails with a scroll bar.
