One of the features of our channel allows users to create slideshows with the photos sourced from a variety of services. One of my customer is having trouble with facebook photos and I've debugged it down to some HTTP issue from the Roku to the server where facebook is hosting the actual image.
I ran into an issue once before with photos from Shutterfly, and it turned out they didn't support range requests, but that has since been resolved (it was only a problem in 3.0 beta, never a production build as far as I know). I suspect this has something to do with HTTPS vs. HTTP
Output from 3.0, build 2227
