Correct, yet what I'm suggesting will make your client work no matter what other clients do. And is still valid. > in this case a _tiny_ change to gajim, or we change all of: > JEP-0153/Psi/Kopete/iChat/PyMSNt/etc/etc. I all for clarification. We should SHA1 the binary representation of the image always. But I still think that even then you should use the hash blindly. For ex: pyMSNt changes the image format from whatever you send to a PNG. If some other server does the same, you might get it wrong.
