Okay... so I have a multi-site with blogs directory and your avatars plugin. I'm having an issue with controlling the display size of the avatar in the list that blog directories plugin creates.
The issue is that the blogs directory plug seems to make a table and inside of the first column, there a site avatar. BUT... and this is the problem part... instead of the image being wrapped in a unique class or something, it has inline styling that forcing it to be 32x32 making any CSS styling I do pointless as the inline overrides it.
So, what I'm asking here is that you update the blogs directory plugin to change the coding of this and/or give backend options to change the display size as it is pretty useless style wise as it stands.
