John/James - Two Suggestions:

1. Can you make use of the STYLE tag?
The style tag is a very important HTML tag that allows you to do anything to FORMAT the text. It's powerful and harmless. Is it OK that you add that tag as a VBCode tag (like [style="borders raised all"])?


2. I think that you should reset the avitar limit to 64. Many pictures on the internet are 16x16, 32x32, and 64x64 (standard ICON rule).
