Make Filename Lowercase

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.
