I also have issues with photo thumbnails after upgrading my Jabber for Windows clients from v9.6 to v10.5(1): in client v9 I have them, but after upgrade to v10, all photo disappeared... I have a mix of Jabber clients: if I search a contact in v9, I see the pic. If I search the same user in Jabber v10, I don't see any pic. My thumbnails are stored in AD, not on a specific server.
What version of UCM are you running? Cant recall if 9.1.2 does but pretty sure with 10.x you can set the CSF device to use a certain jabber config file if you upload your test one with a different name.
If that option does not clearly stand out there maybe a box called Cisco Support Field and updated it to reflect something like this configurationfile=test-config.xml
Just make sure when uploading the different name file upload it to the root of the tftp on all servers and restart the tftp service.
I have it working for Windows but MAC for some reason will not display contact photos when using UDS. FYI, I'm pointing to an external server for pictures like above. I opened a TAC case, hopefully they will be able to explain why.
Get a user to click the cog icon and select reset jabber and login again to see if that helps also try to re-create the jabber-config.xml file using the tool selecting 10.5 as the version, upload and restart tftp services.
Confirm as well that you are using UDS and not using LDAP, cog icon, show connection status to check.
