Syndetics offers different image sizes - results currently use the small size which can appear low res and ugly on some browsers. There should be a configuration option for the library to choose size
Just to clarify, I believe this is to provide a configuration option for cover images on the staff side. The OPAC already has a couple of related system preferences (SyndeticsCoverImages & SyndeticsCoverImageSize).
In the OPAC Syndetics cover sizes are configurable via the system preference 'SyndeticsCoverImageSize'. As for adding Syndetics covers to the staff client, it looks like that is being handled in Bug 21225. Is this bug still valid?
