Getting StumbleUpon profile image in PHP

Hey all,

I am wondering if anyone knows how to in PHP have it so when a StumbleUpon profile URL is submitted it will get the URL of their profile image? The submitting of the URL and everything like that is already in place and working fine it’s just the extra part of it also getting the profile image URL.

I know my way around PHP but have no idea how to go about doing this so any help regarding that would be greatly appreciated.
