I would love to have PIL in sage, and for someone to fix the gd module that Tom Boothby worked on. I guess the advantage of gd is its speed. I think for both of them there are some issues on macs, with the jpeg library, but maybe that's been fixed in PIL now. With gd I remember I finally got it working on my macs but it was a confusing struggle (for me, but I am pretty ignorant about library linking issues).
