Instead of specifying width and height in the querystring like this:
http://example.com/media/cow/small.png?w=100&h=100
Is it possible to configure Imageresizer to look at the filename (small.png) and use this information to scale it to 100x100?
This would allow me to request images like this:
http://example.com/media/cow/small.png
http://example.com/media/cow/big.png
