W3 total cache CND import dont work with picasa photos

There is error when trying to import images from picasa (ggpht, blogspot, blogger) adresses. I think this is regex problem in code, and can be easy fixed.

Image like https://lh6.ggpht.com/_FGo65z9IE_k/Sdk9WXBDxiI/AAAAAAAAHEs/fAavg5KOKg8/%5BUNSET%5D.jpg?imgmax=800
is rejected because url is finishin with code instead of extension. This is must do because all blogs that are transfered from blogger blogs to wordpress and trying to use W3 total cache cant use this awesome importer.
