So you have urls in Sonta Media Bundle similar to this:

http://domain.dev/uploads/media/default/0001/01/thumb_6_ad_default_large.png
http://domain.dev/uploads/media/default/0001/01/thumb_6_ad_defaul_small.png

But you think they'd look much better and SEO friendly like this:

http://domain.dev/uploads/media/default/0001/01/facebook-6-large.png
http://domain.dev/uploads/media/default/0001/01/facebook-6-small.png

Me too! I will show you how to overwrite the core function of the FormatThumbnail.php file to acheive these much better naming schemes.
