codigniter and image download problem

Also, in the download helper, try commenting out anything that sets the content-length. If you have mb string functions overloaded, the content length can be calculated incorrectly and will cut off the end of the file download. Probably not the issue in your case but is worth testing.

Also, how are you fetching/generating the images you are trying to output?
