why didn't you just try the code and checked if it worked?
Anyways i just tested it and it does exactly what it is suppose to, returns true if the two images are exactly the same and false if they are not.

Of course I tried it. The arrays I compared ended up returning false, but I wasn't sure if it was the method of comparison I used that was wrong or if in fact the two arrays were different (which they're not supposed to be).

I asked this question a few weeks ago. I want to know if there is a function that returns where the two are not identical.

As opposed to writing your own algorithm to determine where the two images are different.

If any one has any idea, please post.

depending on what you're doing to those images you're likely to end up with a difference list containing a large percentage of the pixels, all of which differ by tiny amounts of one of the rgb values. they'll look the same, but won't be binary identical.

depending on your needs it might be better to compare those values roughly rather than exactly. and using the HSB* methods might be more appropriate.

*or is it HSV?

As for my problem, I settled with forcing the two images into becoming identical by simply replacing the "faulty" pixels in the destination image with pixels from the source image:
