This feature is not currently supported :-(.

We've been doing a lot of work behind the scenes to improve profile pics on Xanga. We've moved all the pics into a brand new storage system that allows:

• Faster Pics - the new storage system is much faster, so your pics should appear more quickly on the page
  
  
• Higher Quality Pics - the new storage system is much bigger so we're able to save higher quality versions of your profile pics
  
  
• Multiple Profile Pics for Everyone - with the bigger storage system, we can also let every user upload multiple profile pics to use on their Xanga sites, individual entry (comments) pages, and other places in the Xanga Community.

These enhancements weren't just cosmetic tweaks; they arose from fundamental changes to the way we handle profile pics, changes that will let us support lots of other cool features in the future, too (including, rotating profile pics).

Now that we have tons of room on our profile pic servers, and now that they’re blazing fast, we’re really excited about building more cool features for profile pics.
