Hi,
Great mod first of all

Secondly I would like to make a few suggestions which could either be part of the Lite or Pro version - suggestions all the same

1. Popup image
When the user clicks on an image it popup in a small resized window so that users can stay on the gallery index while being able to view images.
An optional and cooler alternative could also be using the 'lightbox' addon which is available from DynamicDrive for free
here2. Zipped Downloads
Users are able to mark images as being "added to cart" and then be able to download them all together as a zip file
3. Batch Upload
Admin would have the ability to batch upload images via FTP to a folder and specify the path and gallery would automatically form the thumbnails and resize them accordingly
4. User galleries
An option for the admin to either enable or disable the user image galleries. If enabled then the images uploaded by a specific member are ALSO indexed on a personal gallery page of theirs APART from being added to the main galleries (if they choose to do so)
When the option is off the gallery simply adds the images to the main galleries created by the admin and no "user personal gallery" index page is created.
Hope you like these suggestions.
Looking forward eagerly to your next release.
