On the net are available some great and free flash based picasa templates: some of them are available at these sites

these are really great, the best galleries I've ever seen, and more are available on other sites... the problem is they're made for picasa

you think it would be possible adapting XnView so that it accepts also these kind of gallery templates? I know it already has it's format, but there are really A LOT of picasa templates on the net, and being able to use them inside xnview would be awsome

Moreover the format seems to be simple so it shouldn't be too hard to do

What do you think?
