Support for multiple style images

[MRLoghmani]

I admit that I didn't dig too much into the code, but by looking at the parser's arguments it seems that multiple style images are not supported yet. Am I correct? Will it be available in the near future?

I unfortunately haven't had time to maintain this code the past several months. If you end up implementing this in your own fork, I'd be happy to merge it into master.
