Loading images from Picasa

Hi everyone,

I was trying to use picasa_ruby gem in my app rails to load picasa
images. But photos aren't loaded although the thumbnails do. I mean,
photo.thumbnails[0].url works but photo.url don't.

It seems to be the same problem as Esdras Mayrink tell us here:
but noboby give a solution there.

Someone knows how to solve this problem?

Thanks for your help.
