My apologies. <_<
What happened was at the exact same time, while you changed it to a url, I already was editing it for a minor typo, and still had the codes on it. Exactly after you modified it to url, not knowing that you'd done so, I clicked modify, which had the original message as well as the typo fix.
I wasn't deliberately changing it back to image codes to just to bug you. Sorry for any misunderstanding. -__-
