OS X bash script to download entire picasaweb albums

I found this great tool to download an entire picasaweb album except it didn’t work in OS X. After a quick search on a couple of man pages I found the difference when using OS X’s mktemp and fixed things. Now I can easily grab my favorite albums from friends and family and load them into iPhoto. What a huge time-saver!
