Help please with Styling Avatar

Hi Folks,

I would like to ask for some assistance with styling the avatar on the following website that I have put together on as a volunteer basis for a Charity,

http://www.merchistounhall.co.uk

I've spent about 20 hours on trying to resolve this issue, and I am just totally at a dead end.

The Avatar is embedded via the ATO options pages not via coding in the default template.

Please let me know about any questions to help diagnose the problem.

Many thanks for any assistance,
Steve
