Album.pl is written in Perl, and it's a one-man show: Mike Bobbit.
Gallery is written in PHP, and it looks like there's at least twelve developers and programmers that contribute to its development.
Personally, I feel that album.pl is supported extremely well. There's nothing like getting support right from the horse's mouth. Mike doesn't have a flashy website like Gallery's because he's spending most of his time helping people (via the forums), adding user-requested features (via the forums), and tweaking his code.
As far as Imagemagick, most ISP's will install it if requested. Many already have it loaded.
Installation of album.pl is one of the easiest things to do: you upload a few files, modify some permissions, and point your photo directory to it. It's a snap. You can have an online photo gallery operational in a few mintues, literally. You don't even NEED ImageMagick or any other programs to be operational.
Gallery looks like it would take me a week to just get it going. Furthermore, you MUST have ImageMagick or Net PBM installed on your server in order for it to work.
However, thanks for pointing out Gallery. I'm always looking at playing with different apps. I'm sure Mike will be interested in checking it out too.
