This is a simple control which can be added to the gallery sidebar, it allows users to upload photos to share from this context... Further it can override the standard gallery permissions, allowing normal or anonymous users to add photos without needing to give them access to the CS Control Panel. It optionally allows the photos uploaded to be moderated by default.

Update 20070516 - I updated the control for CS 2.1 SP3, Including support for gallery quotas. In addition the control now also includes fixes for the AggregatePortalPictureListing (the sidebar picutre list), the GallerySlideshowHandler, and the AggregateUpdatedGalleriesListing (the galleries home page) to honor the "post level default" "Publish to sites aggregate list" setting which was never fully implemented in CS Galleries. And finally, I included a novelty, a remake of Jose Lemas ImageToText CSModule, as an updated GalleryImage control. The source for these are included in the zip.
This control is for CS 2.1 only and will not work with CS 2007 (I should have an updated version available shortly)
You can see / test the control in action at http://blog.danbartels.com/photos/QuickAdd/
