Hello,
there is a Problem with mod_rewrite i think. I have a problem to display all pictures with a "0" in the filename. In Document-Root folder i have a symlink to the folder called "images". This folder is one directory above.
Most pictures are shown in Browser, but some have a "0" in the filename. They cannot be displayed in Browser. If I disable mod_rewrite then where all pictures displayed in Browser. Maybe there is a Bug in mod_rewrite. The filenames of the images have only numbers and they are all jpg-format.
I used following Syntax in file rewrite:

"/images/new/user/thumb/([0-9]+)\.([a-z]+)$" => "/images/new/user/thumb/$1" 

Much thank to you
