You can use EyeConnect on your Mac to access jpeg photos, MP3 files, etc. through Home Media Gallery. Do a Google for EyeConnect to download a thirty day trial version. I did so, and I can access jpeg photos on my Mac and can see music files from my iTunes libray. However, so far I have not figured out how to get the Pioneer to play the music files as anything but static. Everything in my iTunes library is either AAC or Apple Lossless Codec, so that may be my problem.
Anyone else care to chime in with better ideas? Thanks in advance.
