Hi,
you can manage this with CSS, or you can write in your module something like:

<img src="/{user avatar_mini raw}" height="30" width="30" />

NOTE:
1. All image fields have 2 versions (normal and thumb), for example avatar normal size is {user avatar} and avatar thumb is {user avatar_mini}, docs at http://docs.easy-profile.com/index.php/article/content-plugin

2. You can call all field with in "raw" format, for example
{user avatar_mini} -> Return Thumb image
{user avatar_mini raw} -> Return Thumb URL
