Thanks for the suggestion, Brent. I'm using an LDAP backend for  
authentication and personal addressbooks, and I can upload contacts'  
photo's fine.

I'm not 100% certain it is a caching problem anymore.. The cache files  
are getting created fine and the problem persists. The problem is  
still there even if I disable caching altogether.

I must have broken something else somewhere along the line.. I've got  
a spare server waiting to be a hot standby Horde server, so I'll  
probably set that up and get it replicating the databases and file  
systems, then switch all my users over to it before rebuilding the  
current server.

It's still really bugging me that there must be a config file I've got  
wrong somewhere though :-)
