For Scott, Emma, Lavrai and Tom
..and other people experiencing problems with folders with spaces in the name.
I found the bug causing the filemtime error and corrected the problem. The %20 codes from the URI should have been translated back to spaces. 
Also, the Lightbox links have been corrected. The code for the links to the images that weren't on display in Thumbs view or Slide view are now placed in a correct HTML element.
