With multiple records rolling up into one, sometimes the featured cover art visible in Vega for the entire rollup of a title is less than ideal (the image is from record with the newest copyright/publishing date). The only way to remedy this (I've been in touch with Syndetics) is to falsify the original record with an incorrect 020 or remove the 020 completely. It would be nice if libraries could a) manually force an image skip (ie choose the next image available), b) add our own generic images, or c) manually remove the image completely from a record without tampering with the MARC record. Admittedly, this is an occasional issue (we came across a version of Hamlet where the featured image is a very distinct version which not all libraries have), but it would be helpful to have the option.
