sbank, You are correct & I was wrong (sorry). I now know that iTunes does NOT store the album cover art with the song but hides it in another encrypted folder. The explains why my album transfer to the Aurender did NOT display the album cover art. And, yes, I agree, as you stated, Aurender is not responsible since Apple decided to not imbed the album cover art in every song/file in iTunes, like just about every other piece of music software does.
After additional research, I found a custom Script created by Doug Adams that runs in iTunes and saves the album art to the song folder as a JPG file. My dealer technical person reviewed the Script and we decided to run it. Please follow Doug's detailed install instructions carefully since you have to make the Script available in iTunes to run it. The cost is $1.99 and you pay after you install the Script. We checked the results and every album that had album cover art now had a JPG file associated with that song (in the correct folder). I was very happy BUT!!!!!
I deleted my albums on the Aurender and transferred my updated hard drive albums with JPG files included and guess what. Again, I STILL HAD NO album cover art. I could not believe it.
I doubled checked everything and discovered the Aurender did not transfer my JPG files to its library. My dealer person not available. Yes, I was frustrated but I did not give up. It had to be something simple in the transfer process that I missed. I spoke to Aurender Support and was told the JPG files HAVE to be named “Folder.JPG". I immediately tested it on one album and it worked. I then discovered that I used the wrong Script to save my album art. IF YOU ARE USING the Aurender, you have to USE the Save Album Art as folder.jpg v3.4 Script (see below).
"Save Album Art as folder.jpg v3.4"
"OS X 10.8 or later only. This script will export the artwork of the selected tracks or tracks in the selected playlist as a JPEG image file named folder.jpg to the folder which contains each selected track's file--presumably the track's Album folder. Many third-party music players and systems (Sonos, for example) may look for a "folder.jpg" here to use as display artwork. If multiple album tracks are selected, the script will make sure only one image file per Album is exported".

I hope my above explanation helps other people using the Aurender Music Server to get their album cover art displayed. Please contact me if you have any questions.
