I thought the OP was okay but not quite clear enough to be a good pick.
that just looks like JAFAAC to me.
Agreed, for the same reasons as the two above have said
Yeah, I can't tell what this is.
What about one image of Fire Lord Ozai at the peak of his power in Avatar followed by one of him rotting in jail? I'm pretty sure clear cut versions of both would get the message across well.
From what little I know about ATLA, that sounds spoilery.
I can confirm that is literally the end of the series.
Is it still spoilers that Ozai was defeated and thrown in a prison cell? It's been over 10 years since Ozai's downfall and we have other image examples of Zuko surviving to old age and Azula's Villainous Breakdown, which also occurred at the end of the series.
EDIT:

Alright, made this picture of compare and contrast.

The first looks more like a banner than a person, too.
I guess there are better images of Phoenix King Ozai. This one was quickly made based off of images I found on the Avatar Wiki.
What episodes are the screenshots from?
19, but would prefer a brighter version of the bottom image (I find it hard to make out).
I agree, can't really see the bottom photo too.
This image
