Thanks for the input and sorry for the late response. Just realised posting on this forum had not been turned on ... oops !!
There's actually been a lot of improvements added to this site recently, including image handling. There's no facility to import
pictures directly from Discogs inventory but users can load their own images directly per item.
Otherwise, anything listed with a Discogs 'release_id' number will get an image automatically generated if nothing is added by
the owner of the listing.
