Item Display Considerations
Using images in your exhibit
The Spotlight exhibits application was specifically designed to showcase visual collections. While its use has expanded to include text documents, data, video and audio, the underlying purpose of the application design is intended to engage the exhibit visitor's interest using visual means, alongside the textual context provided by the exhibit creator. For selected exhibits, this provides an opportunity for the exhibit creator to enhance viewer engagement by including images on the home page, for browse category tiles, and elsewhere as desired. Here are a couple of ideas for adding images to exhibits that have text-heavy content:
- Some text-heavy content includes compelling graphics or diagrams. The Joint Committee on Atomic Energy is one such example. A relevant and interesting diagram was located on a page of one of the reports in the exhibit, and used to create visual interest on the home page.
- Research from Stanford University showcases research data from across the university. The data sets were typically not accompanied by compelling imagery, but the exhibit creator was able to locate copyright-free, colorful and relevant images to use as browse category thumbnails. For good sources of copyright-free images, check out Unsplash, or do an advanced search on Google Images or Flickr.
- Please note that image uploads for non-SDR content, such as an image uploaded from your desktop for the main exhibit tile, or an image used on a feature page that is uploaded from another location like box or Google Drive, for example -- are limited to no more than 10 MB per image. Uploaded files are restricted to the following file formats: PNG, JPG or JPEG.
Please see the browse category Video for examples. As stated in the browse category description, some videos will have anchor images, while other videos will not. Where you see a thumbnail image of the media itself, this is not considered an anchor image. Alternatively, videos without an anchor image may not display a thumbnail image in any browse view category. Videos with an anchor image (which will also appear as a thumbnail) will display an image on the Item Details page -- in the viewing/playback window before the video playback is started. Adding an anchor image is custom work for the Stanford Media Preservation Lab, and for the Stanford Digital Repository accessioning process. Without an anchor image, on the record view page videos will display as a black screen to start, with the playback push-to-start arrow in the upper left-hand corner of the viewer.
Please see the browse category Audio for examples. As stated in the browse category description and similar to video display, some audio objects will display either thumbnail images of the media itself or an anchor image if one was provided when the audio file was added to the SDR. Other audio objects will not display a thumbnail image in any browse view category. Audios will either display as a black screen to start, or display a custom-added anchor image on the Item Details page, with the playback push-to-start arrow in the upper left-hand corner of the viewer.
World-accessible PDFs display in the sul-embed viewer that is used by Spotlight exhibits, and also by PURL pages and in SearchWorks. PDFs with restricted access: world-no download, Stanford, or Stanford-no download will not display in the viewer. Future work on the sul-embed viewer, which leverages the current version of Mirador -- may change this restriction when the community is able to prioritize work on access controls for restricted content.
Hiding exhibit items from public view - for items added in error
Sometimes objects are added to an exhibit in error. It is easy to suppress viewing of these objects in your exhibit, by navigating to each object and checking the box marked private in the upper right-hand corner. You may also mark items as private by navigating to the Items page in the Curation sub-menu and unchecking the appropriate box in the Public column on the right. You can see which items you have hidden and which are public by using the facets. To do this, click on the magnifying glass in the upper right-hand corner, with no search terms entered. Look at the facets on your left, and you will see a facet called Item Visibility. This will list all of the objects you have marked as private, and they will not show up to exhibit visitors when your exhibit is published.
Currently, it is not possible to remove objects from an exhibit once they have been added. We have prioritized the ability for objects to be in multiple exhibits, as well as allowing for the addition of both collection and object-level druids (unique identifiers) from the Stanford Digital Repository to an exhibit. This creates a complex technical landscape for object removal from an exhibit.
