Hi Wanangwa, To add a thumbnail to an existing item, you'll need to upload it as a bitstream under the Thumbnail bundle (See Edit Bitstream documentation <https://wiki.lyrasis.org/display/DSDOC9x/Edit+Bitstream>). Is there a particular step in there that has not been working? Alternatively if you need to auto-generate thumbnails for many existing items, you could look into the media filters script <https://wiki.lyrasis.org/display/DSDOC9x/Mediafilters+for+Transforming+DSpace+Content>. There are several filters for creating thumbnails based on PDFs.
Last, there is not currently a PDF viewer integrated with DSpace. There is an implementation that is under review <https://github.com/DSpace/dspace-angular/pull/5144>, and could theoretically become a part of the 10.0 release (but that is still unknown, not guaranteed). Hope that helps you get started, -Lia On Friday, February 27, 2026 at 7:38:38 AM UTC-5 [email protected] wrote: > Hello there follow users.
