So I wanted to change my Youtube avatar, and when I make comments and look at previous ones, it doesn't change! So then I close out and Chrome and Re-open it. Doesn't work. I restart my computer. DOESN'T WORK. I take out my new avatar, swap it, and put the new one back in. Guess what? DOESN'T WORK!

Yah know what's even more frustrating? When I change my avatar, on the preview view, it doesn't even display the new one!

Ask them.

I'm OCD when it comes to pictures.

isnt it tied into your gmail / google account?

maybe changing your avatar pic over there will fix it on youtube.

I haven't tried it, but that's my guess, too.

Google has had such a hardon for Google+ and forcing people to use real names. As such, you're going to end up finding that your core Google Account will control a LOT of things.
