Ok, but the avatars In the posts are all the same size right? -- The member panel I'll look at, and the other page those look appropriate. Your right, the images are resized based on where they are being used, what browser the reader is using, etc.
Yes, but they aren't right internally. The profile ones are a bit better. Let me try to describe what I mean about the ones in the posts and click on my first attachment above as an example since apparently its not happening to you.

When I look at JimHarvard's post, he's missing the top of his head. Click on his picture or screen name and the version in the black box he gets his whole head and even his hat!
Similarly, in Mycuda's posts, the image is of a car from the windshield back. But when viewed in the black box, the whole car is there.

So it seems ALL the post avatars have a fixed frame dimension of W x H. Lets say its 120 pix x 120 pixels (I'm just making up numbers as an example). I know my avatar jpg was 80 x 58 pixels to meet the old rules and look OK. It looks like the height, 58 pixels, was expanded to fill the 120 pixel frame height, and the 80 pixels was expanded proportionally, so the jpg became 160 wide. But the frame is is only 120 wide, so 40 pixels of width are cut off.
Again that's just to explain what it looks like is happening. It cant be the correct explanation or JimHarvard wouldn't be losing his hat!
