Bug 34724: (QA follow-up):

Replace href from thumbnail link with a # to keep pointer event. The href link gets reconstructed by showCover anyway
Remove return false from on click event, its not triggering a location change anymore because of the above
Remove check for imagenumber, its a non-null primary key, if the image exists, then the imagenumber must also exist
