In our XenApp 6.5 farm, image preview in Windows Explorer is disabled via Group Policy. This is to reduce the required bandwidth and 99% of our users don't really use that many images. However there is that 1% that do. I could exclude these users from the policy, but to be honest the Windows explorer previewing in any RDP or XenApp session sucks balls. The thumbnails takes ages to populate and you have to scroll through all of them so they show.
Just wondering what other administrators experiences with this are? Would you tell the users to "suck it" or is there a 3rd party app I should look at (eg Picasa or some other free tool).
