Please stop adding that image to the page: the page is rather short, and there is simply no room for an extra image. Your reasoning for why Bujing was smirking/frowing is pure speculation, which is something we don't add, and you edit removed all the interwiki links and categories. For all those reasons, your edit has been rightfully undone each time. The only acceptable change was the "smirking" to "frowing", which I have added back. So with that, I hope that you will stop this edit war.
I do not understand why there is no room for the other picture, since other short pages have had 2 pictures, not including the "character"'s or "place"'s main big picture. Besides that, I would think the page would be better with that picture, since it shows more of Bujing's main point in Zuko's history, rather than the other, when he is looking at another general after Zuko has returned home.
http://avatar.wikia.com/wiki/Dancing_Dragon This is a quite a short article, and although it has more than 1 "section" other than trivia or references, as usual, the sections are small and it still has more than 1 picture.
Their length and build-up are not comparable at all, the main difference being that the Dancing Dragon article doesn't have an infobox. Bujing's page does and with one image already next to it, another underneath it gives a very cluttered vibe, which is undesirable. So it's really not about the amount of sections, it's about the placement and the spaciness of the images, which is fine on the Dancing Dragon article, but not on Bujing's with the additional image.
I thought their length was quite similar and comparable enough.
Very well, but I still think the picture I tried to add would be a good picture of him, especially when in the History section, since it is more important than just looking at General Shinu when Zuko is in a "better" war meeting. And it took a LONG time to even get the picture on the article for some reason.
I understand that there is no speculation, but I forgot and was merely trying to give a reason of why Bujing would frown instead of smirk, since would he, despite his plan being insulted, now not like Ozai to burn and banish his own son? Could he have been disappointed that he didn't get to duel Zuko? Although we won't know, it is interesting why he was frowning.
Regardless of the reason, do you actually agree that Bujing was frowning, while Zhao and Azula were the people smirking, or are you just writing that for no more edit war?
When the screen zooms in on Iroh looking away in the flashback, and there is a goof of his hair being "invisible" that I added, you can see Bujing's face much better and in the close-up see that he actually has a particular emotion of frowning.
