Ok, you switched it out of Safe Mode now. Good.
Example:
http://www.artanderotica.com/1/0/8/2...copy_thumb.jpg
Should be:
http://www.artanderotica.com/gallery...copy_thumb.jpg (At least, with a default install. If you changed the location of your "Files" directory, adjust accordingly.)
Under AdminCP->Gallery->Modify Settings make sure that the "Files Path" and "Files URL" are still intact and are correct. That's what is used to build those paths...
