## Popis

Sets uploaded media filename to lowercase as filter on sanitize_file_name. Based
on post at Stack Overflow asking if there is a way to „Rename files during upload
within WordPress 3.0 backend“.

Created for WordPress 3.0.1+ which saves any uploaded media filename (Image, Video,
Audio) as lowercase. This effectively changes the name of the file at upload if 
a user were to upload a file with any uppercase characters.

For instance:

 * MOVIE-FILE.MOV > movie-file.mov
 * Movie-File.wmv > movie-file.wmv
 * ImAgEfILe.gif > imagefile.gif
 * imageFile.JPG > imagefile.jpg
 * ETC > etc

_Note: WordPress sets file extension to lowercase. This plugin does a strtolower
on the filename._

## Nejčastější dotazy

### Why was this plugin created?

This plugin evolved from a client requirement that all uploaded media filenames 
contain no uppercase characters.

### Why did you release this plugin?

It was useful to me and I wanted to work through the process of releasing a WordPress
plugin.

### Why shouldn’t this just be added to a theme’s functions.php file?

Upgradeability, portability, backwards compatibility, and other *abilities. If for
some reason this function were in need of customization due to a WordPress version
upgrade, the plugin will be centrally responsible for releasing the fix as opposed
to updating the theme(s).
