As far as I can see your code looks fine, and running in the simulator (where plenty of memory) this should be working. A few suggestions:

1) use dataWithContentsOfFile:options:error: instead of dataWithContentsOfFile:, use the NSDataReadingUncached option (to reduce memory pressure on the system), and test the return value - if nil log the error and update your question.

2) You can always dump the data image in a NSCache object, and if the system needs memory it will release cache items, and you'll have to re-read the image from the file system. You can use this technique even if you only pull a few images at a time.

3) You can use UIImage imageWithContentsOfFile: instead of getting the data then creating the image. In this case put the UIImage itself in the cache, with a key of its name.
