Are you wanting to compare parts of the original file (which may change due to compression etc) or are you trying to compare pixel colours etc?

Or do you just want to convert the raw binary data into a string?

Or do you just want to compare to jpg's?

I've found lots of information on how a jpg's data is structured but not on how to convert it to a form that can be read. No text in the image.

thank you that was simple and to the point appreciate it. will give it a shot.
