Artwork for files

Hi, after i transferred all my files from OTS AV Pro DJ to my ssd drive that i have put in prime 4, none of my artwork comes across now for albums/tracks. What is the best program to download artwork from 600x600jpg and then is there aneasy way to put all onto internal ssd in prime 4 or do i have to start all over again

Hi, I reworked all my tracks who had no covers (older ones) with mp3tag and searched for covers with AAD (Album Art Downloader). You can implement AAD in mp3tag. When you find the correct cover you have to save it to the track. After that in Engine Prime you have to reimport the track information to see your covers. But thats a lot of work if you have a big collection. Greets
