Add an option to the OPAC to display the URI that is stored in the 856u field as an image instead of a text link. This would be implemented in the OPAC XSLT style sheets for the Results and Details pages, and would require that the corresponding OPAC XSLT option be set. This enhancement is designed to enable the staff to catalog images, then have them appear on the resulting pages in the OPAC when searching. Clicking on the image would open it full size. If the image option is in use, then the default link text would be disabled. Custom text would still appear if entered in the "URLLinkText" option. Add system preference "Display856uAsImage" with options of Results page, Details page, Both Results and Details pages, Neither Results or Details page. Notes for documentation manager: There are two system preferences added for this enhancement: OPACDisplay856uAsImage and Display856uAsImage. These appear on the OPAC and Staff Client screens under the System Preferences. The preference can be set to one of four options: Both Details and Results pages Details page only Neither Details or Results pages Results page only In addition to this option being set, the corresponding XSLT option must be turned on. Also, the corresponding 856q field must have a valid MIME image extension (e.g., "jpg") or MIME image type (i.e. starting with "image/"), or the generic indicator "img" entered in the field. As of 14 March 2011 the UNIMARC xslt display files also require a "0" in the second indicator location of the 856u field for the links to be activated. This is not true for the MARC21 display files. When all of the requirements are met, an image file will be displayed instead of the standard link text. Clicking on the image will open it in the same way as clicking on the link text. Rebased and three original patches squashed into one on 30 March 2011 by Jared Camins-Esakov.
