I've posted a new build for Simple Gallery in the downloads section (members only).

New Functionality Includes:-

• Extended Functionality for Random Photos!
• Display photos by either Random or Latest Added, select the max # of pics to display, control the repeat direction & repeat columns (e.g. 3 per row). See example here.

Fixed Bugs Include:-

• Only approved photos will appear in the random module.
• Approve screen is now module specific.

Thanks again for all your feedback! Keep voting and I'm looking forward to hearing feedback on the photo moderation functionality.
