Oh, alright :0 If you ever change another template image in the future, it's usually more polite to make a vote and easier, as someone could undo your edit adding a new png on the basis of there being no vote first to change the png.

You aren't breaking any rules if you don't make a vote first though, but if you add one without a vote and an edit war breaks out over it, then I'd make a vote.
