https://bugs.koha-community.org/bugzilla3/show_bug.cgi?id=33193 --- Comment #1 from Katrin Fischer <katrin.fischer@bsz-bw.de> --- I feel like this is asking too much of CustomCoverImagesURL. In order to make this work, we'd need a complex way to specificy which repeated fields it should look at. In this case we'd need to be able to specify that it also should filter on $q being image. Especially since $q is not cataloged to the standard here: https://www.loc.gov/marc/bibliographic/bd856.html $q - Electronic format type Identification of the electronic format type and version. Electronic format type should be specified with a code from the list of registered Internet Media Types (MIME types), taken from: IANA Media Types. If necessary (e.g., in order to specify a file format version to support access or digital preservation) additional information, such as PRONOM Unique Identifier (PUID) codes, may be included in addition to the information provided by the MIME Type by repeating subfield $q. Maybe OPACDisplay856uAsImage would work better here or we could improve on that pref. -- You are receiving this mail because: You are the assignee for the bug. You are watching all bug changes.
