Thanks again for the tip. I have now updated the script’s itunes support to fetch the genuine size. @jesus2099, I took the liberty of copying your itunes regexp directly into my code (with credit). It was pure plug&play. I hope it’s okay.
I also updated the support for itunes search-engines fnd.io, labs.stephenou.com/itunes and musicdiner.com. You can get the genuine sized covers directly from these sites without following links to itunes first.
