Changing the User Pictures source

I love how simple this module is - though would love to see a couple of options added to make it more of an integrated experience.

First up, the admin area @ admin/config/drupalchat/configuration lets you choose to display User Pictures in the chat area but doesn't let you choose an image field to use - so you're stuck with default drupal user pictures, which hardly anyone uses in favor of custom imagefields... Anyway to add this? Anyone know of a work-around?

Thanks,
Qasim
