Was having trouble with the gallery and the images not showing up. After some short debugging, realized the code was dying when I tried to make sure the file existed using is_file before I passed it onto GD. I spent hours looking at the path for the file and making sure everything was spelled correctly and that the file in fact did exist.

After spending most of a day on the issue I decided to look at the php.net documentation of the file. What I found in the comments was the root of my problem. Apparently the function is_file can not read files larger than ~2.1 billion bytes. My images where only on average 1MB. I wound up removing that code. Need to look into if file_exists() has the same problem.
