NVIDIA Releases DALI Library & nvJPEG GPU-Accelerated Library For JPEG Decode

He was most likely referring to Raw images taken with a DSLR camera, they get big, 40MB per picture or more. If the JPEG's are doing it, it's most likely the programs default adjutsments for viewing to liven them up a little.

But obviously this tech is for where you would need to decode massive amounts of jpeg data, like searching for a specific person via real-time face detection or whatever else they are cooking up...

True raw imagines can be slow. Though 40MB from a fast disk still doesn't take any significant time, but they can be very slow if you load them from a cameras flash-disk, though they also come in different speeds. And you would also be right, if the viewer does image processing on the CPU, that could also be very slow, and raw images in HDR and other fun things do need that before you can even show them. For images in the 10s of megapixels, you really need hardware accelerated image processing, or you are going to be waiting a bit.
