I wasn’t aware my Art Grabr didn’t work anymore on cdbaby until I coincidentally stumbled over this thread. People are always welcome to give me a hint if it stops working somewhere. It might take long time before I discover it myself.
Anyway, I have now updated Stig’s Art Grabr with a fix for cdbaby. I haven’t tried shopping at the site, so I don’t know what you get access to when purchasing something, but it should generally be able to find a bit larger sizes while surfing their public catalog.
