A new widget type showing a single user-uploaded image with no live upstream to poll -- decoded once at upload time (PDF's first page via pypdfium2, BSD-3-Clause/Apache-2.0, no copyleft exposure) into plain RGB PNG bytes, then composed per a crop/stretch/letterbox display mode like the photos widget.
