As I explained above, if you are using iTunes, you have to download the Extract to Folder.jpg Script from Doug Scripts (cost is $1.99). The Script run process is vey easy but it takes time depending on the number of albums (Do not copy all your files at one time. Do it in small batches). This script is required since it stores the album cover art image in the CORRECT location and includes the CORRECT name (Folder.jpg) for handling by the Aurender. Please check the Script for any updates. This very simple, to use script copies the encrypted, hidden album cover art to the correct location for an easy copy over to your Aurender. The process is fairly easy once you know what to do.
In summary, iTunes does NOT STORE the album cover art within the album folder but "HIDES" it in another encrypted and hidden folder. This means the Aurender setup coming from iTunes requires you to run Doug Scripts to extract the album cover art in your transfer process.
NOTE: Please remember that the Aurender requires the album cover art to be stored with the music files and named folder.jpg. The correct album cover art file naming will enable the cover art to be displayed on the Aurender iPad app. I am going to repeat this since the first time I ran Doug's Scripts, I selected the wrong program (whoops, my error). You have to SELECT the "Extract to Folder.jpg Script" from Doug Scripts (cost is $1.99). This naming enable the Aurender to display the album's cover art on the iPad. The scrip stored the Folder.jpg file in the correct location (included in the album).
I hope the above helps. It took me 2+ weeks of total frustration until I discovered the above steps. If needed, an email to support@aurender.com should get you some assistance.
