a newbie question regarding regex in nginx conf

[Chris Savery]

I'm curious about your breaking up the filename into a path like that. 
If using ext3 filesystem is there any advantage speed wise to doing 
that? I thought it could handle large file counts without a problem 
using indexing but I may be wrong and I am quite interested as I expect 
to have thousands of image files as well and if it's going to be slow on 
ext3 then I would also want to split up directories like this.
