User icons width issue when using facebook connect - BP Corporate

Http://stealthfiction.com

If you look at the members list on the homepage and also the recently active members avatars in the footer, all the users who registered via facebook have a wider thumbnail pic than they should.

Can anyone tell me what I need to change to fix the width of the facebook generated avatars?

Also, the size of the avatars in the recently active members widget are much smaller overall after upgrading from BP- Corporate 1.4 to 1.5. (issue with width for FB users was not perviously a factor in this widget.) If possible I would like to adjust the size of those as well.
