I have made a little add-on for those who are interested.
If you want a paperclip with a link to that user's portfolio to show up in your postbit below each user's username/avatar etc. then add the following code wherever it suits:
Code:
<a href="viPortfolio.php?&userid=$userinfo[userid]&action=view"><img src="images/paperclip.gif" alt="View $post[username]'s portfolio" border="0">
Check the screenshot provided to get a clue on what I mean. I believe this will encourage more members to add pics to the portfolio's without adding an extra query per post. I thought it was shame members didn't use this hack simply because they hadn't noticed it, but now they certainly will
