Sig was changed for "size" even though it wasn't too big?

[MLPforever]

My current signature was changed earlier today to the "big bertha" sig for being too big.  But it is exactly 500 by 200.  What gives?

[MaronaPossessed]

Maybe because it includes text too by the size. Maybe lower the height ratio by 400?

I never had a problem with my previous sig, which was the exact same except for the contents of the pic.  But if I wanted to change the height ratio, how would I do that?

It may have been the weight of the image. That's an aspect that I've missed before too. I believe the weight limit is 60.

What does "weight" refer to?

There are 3 size properties to any image:

- width and height - the physical dimensions
- weight - the file size

The weight limit is 60 KB (as was indicated in your visiting Big Bertha banner, and the stickied thread).... yours is sitting at 89.36 KB.
