Ah, so your concern is that the code signature will not be found because the
image encoder obfuscates it?

How is that different from any other obfuscation method applied to code that's
fetched with XHR?

What's the attack model here?  Is the code calling eval() actively trying to
smuggle in code somewhere, such that it's cooperating with the server the image
is coming from to do so?  Or is the server an attacker while the code calling
eval() is not trying to do anything bad?
