You can see other picture sizes available on the User FQL table information page.The URL to the largest-sized profile picture for the user being queried. The image can have a maximum width of 200px and a maximum height of 600px. This URL may be blank
The profile picture dimensions are set by the admin, not the user, since you know your template and where the avatar would be used. Not sure how the user on your site would (or should) be able to configure that.I'd also like to change the CB Profile config interface so the user can select the picture size /type.
