I have a question...Is Utusho supposedly stupid for a reason other than being a "bird", was she dropped on the head as a baby? Ravens are actually pretty smart, and I don't just mean compared to other birds, they're like dolphins where people debate if they are more intelligent than humans and whatnot. Even simple crows are pretty darn smart compared to most animals (and not just birds).
I see many questions relating to Utsuho and stupidity, but other than the fact that she's officially stupid (By ZUN) people suggest some of the following...
*WARNING!!: all of the following are POSSIBILITIES and if somebody says "ZUN may have "unintentionally" made Utsuho stupid." there is no counter.* 1)Maybe she's smart but doesn't like using her head.This is something that was suggested by people who said that "Although she's supposed to be stupid she uses lots of complex words and understands stuff like nuclear fusion." Also from her conversations on the .txt she sounds as if she doesn't think too deeply on what she's goig to do. So maybe she is not stupid but maybe a bit too lazy to think properly...
2)Maybe she is mentally challenged?She can only vaguely remember the god that gave her the power of nuclear fusion... (Not to mention one of them having A large shimenawa and multiple onbashiras on her back)
Also, in 12.3 she said "Oh it's a Miko,
I can't tell the difference between them" to Reimu or Sanae when she wins against either... Not being able to tell the difference (Unless she was intentionally mocking Reimu or Sanae which I doubt from her personality.) Yet she also thinks up of stuff like metal fixing using her powers (When she wins against Youmu). Maybe she has mental problems? Something like Dementia?
3)Political references?Think back to the time when SA was made, -although it was always a problem- the problem of some countries stating their right of possession of Nuclear weapons and some countries actually arming them selves with them (Not to mention missile tests going on at the same time.) In the music room ZUN comments
" I understand very well that even a fool that possesses great power can't cause too much harm. Ah, even if it's the power of dreams. " (Extract from Touhou wiki) So some people imagine Utsuho's stupidity being a small joke towards the politics concerning nuclear weapons. (Although there's nothing about ZUN saying yes or no to Nuclear weapons)
There are other suggestions like; since ZUN makes his music first, since the music sounded a bit light headed Utsuho became a stupid character, or there being a Japanese equivalent of the word "Bird brain" (quite literally) but those are some of the "stronger" arguments for her stupidity. ... I can't cite where all of these were from since I did half by my memory on what was happening on 2ch, NicoNico thread ...etc. But that's all that I can say for the hell crow that I like so much.
Apologies to make it such a long reply, and to Utsuho for not being able to find too many counter arguments...
P.S. Quite recently, I saw someone say,
"It's like Utsuho has a really awesome video card, but she lacks CPU ans RAM."-Random NicoNico person
I thought this was a cleaver way of explaining it, so, I squeezed it in here.
P.S. As for the question by Thundr_Pwnage
I'm sorry but I don't know much except for the facts that:
-It does not work well (or at all) with .jpg
-It has to do with the first colour (top left) on your colour palette you can edit this using specific software. (Photoshop probably works)
-formats like .bmp saves colour pallete information.
