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

New Functionality Includes:-

• New sort order option: Filename

Fixed Bugs Include:-

• Caching from the handler disabled since it causes problems when people changed home directories.
• Editing a photo and supplying nothing for the name will no longer throw an error (validator re-added for updates only)
• Child Portals & RSS feeds should now be fixed (ImageThumbnail was an invalid link)
• Photos are now aligned to the top when viewing photo(s) inside an album.
• Removed redundant style="border:4px solid white" from a few places (it is in the stylesheet if you want to customize)
• Disabled the IE Toolbar in the slideshowpopup screen
• Moved title and description below image on popup screen for consistency with other screens.
• Popup window can now be resized by the user. (although it is best to set an appropriate default in view options)

Thanks again for all your feedback!
