Forum Upgrade and Custom User Avatars
 

Quick question for the pros. I am putting a plan together to go from 3.8.x to 4.x, I might delete everything from my /forums directory and then install the upgrade on a fresh set of uploaded VB files (I would like to get rid of 4+ years worth of miscellaneous orphaned files).

That being said, here is my question: Where are the user's uploaded avatars stored, is it in the database or are they stored in one of the vb directories? What about Sig Pics and Album Photos?
