The spinning icon on the OPAC detail view doesn't disappear, even when covers are displayed. I found this following the test plan from bug 34724, but the behaviour is the same on master: Test plan: 0. Apply the patch (including dependent patches) 1. Go to http://localhost:8081/cgi-bin/koha/admin/preferences.pl?tab=&op=search&searchfield=localcover 2. Change both *LocalCoverImages sysprefs to "Show" 3. Go to http://localhost:8081/cgi-bin/koha/admin/preferences.pl?tab=&op=search&searchfield=AllowMultipleCovers 4. Change "AllowMultipleCovers" to "Allow" 5. Go to http://localhost:8081/cgi-bin/koha/catalogue/detail.pl?biblionumber=29 6. Click "Images (0)" tab 7. Download or make two JPEG images 8. Upload the images 9. Go to http://localhost:8080/cgi-bin/koha/opac-imageviewer.pl?biblionumber=29 10. See one large image in the centre and two smaller thumbnails on the right side
