create an image which displays its end MD5 sum in the image itself

So an executable image?

Can I use ImageMagick or GD to append the MD5 on the image as a layer that gets flattened or as frame of its own? But of course if this was to make the image indistinguishable from copies, MD5 is not suitable, and there are other better methods.

No, an image which depicts its MD5 sum in image form. As long as it's legible, it doesn't matter what it looks like, or what else is in the background of the image. It could look like a captcha for all I care.
Instead of having an image of a car, tree, etc. it's an image which depicts text showing its own MD5 sum. And I don't mean taking an image and superimposing a textual layer which shows the MD5 sum of the previous image. I mean the image has to show its own MD5 sum.

And no, the text layer cannot be standalone or dependent on other software. It has to be deployable and independent of individual 3rd party applications. The MD5 sum depicted in the image must be a part of the image itself rather than a separate layer/file. The image must be a single file, and must be rasterized too.

And if you don't like MD5, suggest another option for a check sum?

Are you fucking retarded? It's very clear what the challenge is.

Ok, you are asking for a new flattened image that contains the main image's MD5 sum, no requirements on placemen or position, as long as it is visible. This could be done in a simple .sh script that calls MD5(1). Are you asking any other requirements?

Unless you are asking for the image that includes the MD5 transposition/layer as part of its value, like a recursive algorithm asking the MD5 value while it publishes its transposition?

yes, that's it

I have no idea how to do that.

#!/usr/bin/perl -l
use bignum;
for($i = 0; $i < 0xFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFF; $i++) {
    $x = sprintf("%032x", $i);
    `convert label:$x $x.png`;
    $md5 = `md5sum $x.png | awk '{print $1}'`;
    print "found one: $x" if ($md5 eq $x);
    unlink "$x.png";
}
Might take a little while to run and no guarantee it will produce any results.

WTF is MD5 transposition?
