The Viewers page is primarily intended to enable you to select the viewer that is used to display a image resource on its Item Details page. It can also be used to specify a IIIF manifest URL pattern for retrieving exhibit items, although that is not currently relevant for most exhibits.
Item detail page
The Item Detail Page tab enables you to select which viewer is used to display image resources on your exhibit's Item Detail page. By default, the Item Detail page in an exhibit uses SUL-Embed as the viewer. You do, however, have the option of making Mirador the viewer for your exhibit's Item Detail Page. To change the viewer, select the Mirador radio button from the Viewer options.
Please note, if you have both image and media (audio and/or video) resources in your exhibit, you must keep the default selection of the sul-embed viewer. The viewer selection applies to all resources in your exhibit. The Mirador viewer does not display audio or video resources.
The SUL-Embed viewer is the same viewer used in other SUL applications, such as SearchWorks and PURL pages. It offers common image viewing features such as zoom, pan, and rotate, as well as full-screen viewing, item metadata, attribution information, download options (depending on the item rights), and code that can be copied and pasted to embed the item into another web application. For most exhibits, the SUL-Embed viewer is the most appropriate viewer to use.
The Mirador viewer is most appropriate for exhibits that contain multi-page image objects, such as manuscripts, or if you expect visitors to use your exhibit for tasks that involve close examination of images.
Mirador provides several ways to navigate the items of a multi-page object and provides options to view items in different ways (book view, scroll view, and gallery view). It also offers, in addition to standard image viewer features like zoom and pan, more advanced image manipulation features such as brightness, contrast, saturation, and grayscale controls.
The Mirador viewer, however, takes up more space on the Item Detail page and its more advanced features might be more of a distraction than a benefit for many users, so select this option only if you are sure it makes sense for your exhibit and its intended audience.
Please note, the Mirador viewer can't be selected for an exhibit that contains audio or video content in the Stanford Digital Repository, or uploaded image content from an external source.
To see an example of the Mirador viewer in a SUL exhibit, check out the Parker Library On The Web exhibit.
The IIIF Manifests tab is not relevant for many SUL exhibits. Its purpose is to provide a IIIF manifest URL pattern to be programmatically used to retrieve exhibit items for display in the exhibit Item Detail page. However, this is currently not a common scenario. If you think your exhibit does require this feature, contact the Spotlight at Stanford service team to discuss the details.
