[development] Shortening file names downloaded from webpage

If uniqueness is an issue, 
http://us2.php.net/manual/en/function.md5-file.php may be good in 
conjunction with a sanitized file name.

For one site with public uploads, I use [sanitized and shortened file 
name]-[md5 of file].[ext], which ensures duplicate files will overwrite 
each other but otherwise you don't have to really worry about the file 
names being unique.

Using [md5 of file].[ext] only means much less helpful file names when 
downloaded and a much larger (but still small) chance of collisions.
