Album link not complete

Hi,

I'm trying out Picasa at the moment, and I like it so far. During testing I discovered a bug: when looking at a single picture, the link to the album is missing the last part of the url, the node number.
I had a look into the source code and fixed it by moving a line up, see attached diff, so that $album is always initialized. Maybe you can have a look at it and put the patch to cvs.

Thx, Marc
