Thanks for that, I passed a third arguement $error and now ALL the errors are the same Data stream is not a known image file format but I don't see how that is. All the images are JPG files with full URLs.

For example http://images.imagefap.com/images/full/9/144/1448694657.jpg returns with that error (it's a clean picture). What could cause this error then? Could the server possibly loaded too slow and it timed out?
