Ok, i have SimplePic fixed! The problem was the new host did not have image magick installed, which is the image resize program, so it couldn't create thumbnails or intermediate images, thus, it failed. I switched to GD v2.x and it's working fine now.
I grabbed Tim's images and my images and uploaded them to the public album "Reading 2008" at simplepic, so folks can view with thumbnails all the images there. Hope you don't mind Tim.

Also, anyone who creates an account there has access to upload to the public folder "Reading 2008" as well as their individual folders. Also, comments are enabled, which is the reason for requiring email verification so we don't get spammed again.
Enjoy the pictures!
