You don't have to process all of your images at the same time. You can just loop through each of them, reading them from the hard drive.

Is this just a random thing, or does it only happen when you run a certain controller, or a certain condition is met? What are the contents of the cookie? Is it encrypted? Do you still get the problem when you disable database sessions?
