Can apple tv2 show raw photo files

Question

Using Apple tv2 in a windows 7 home network environment. Music files and photo files (both JPEG and RAW files) stored on Synology network disk.
Typically I shoot photos in Canon Camera Raw format and store. My wife shoots in JPEG format.
We are using the screensaver in apple tv to show our photos, and it's not obvious whether I need to convert the raw files over to jpeg  in order for those photos to show on the slide show when apple tv is operating.
Can apple tv display raw format photo files?

Answer 1

Whatever iTunes does to populate the AppleTV2 with user photos I have no doubt it will not be sending the original images, only derivatives thereof - if Windows can natively decode these RAW files I suspect iTunes uses them 'As Shot' and then downscales to a lower quality compressed version to send to the AppleTV - if it did not do this AppleTV would not be able to hold many photos from modern cameras due to their resolution and file sizes which would particularly be an issue with RAW files.
AppleTV has 8GB of solid state memory - we don't know how much is available for photos and other tasks, but depending on the camera I doubt you'd get that many RAWs to it if it transferred them as is.
Bear in mind AppleTV 2 can only output 720p quality max which equates to a resolution of 1280x720 so having photos much larger than that (maybe add 50-100% to allow for zooms) is probably not going to help in terms of visual quality.
You might not want a set of redundant smaller JPGs just for AppleTV but they probably wouldn't that much space if you batch processed them to a suitable size.
