Need a Picture preview option for XenApp 6.5 published Desktops

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).

The issue boils down to quantity of pictures, the size of the thumbnails, and the color depth.  3rd party software is not going to address this issue at all -- you will always have the same issue.

Your best steps to address this:
1. Reduce the number of pictures per folder -- by far the *biggest* benefit. Do more segregation into more folders.
2. Limit your color depth -- the small the color depth, the less bandwidth required for the thumbnails, since they will be smaller.
3. Use the smallest thumbnail/preview size.

To address this with the tools you have, you also need to look at the policies.  Turn on progressive display, turn on ultra high compression (it really is not nearly as much overhead as they make it sound).  There are a few options to tinker with that can greatly improve the speed.  Depending on your hardware & clients, you can take advantage of HDX3DPro with it's ultra high compression (it uses the GPU on the server to compress the graphics, and you need NVidia graphics cards for it..
