Original request:

ideally, in the work record view, the app would display a few images (that can be lower res than the original) so that users can be sure that this is indeed the version they're looking for.

I think the easiest solution will be to download the manifest for a work or a work part (see the API), and construct the image URLs from there.

I've created an endpoint that combines both (through IIIF). For instance if you want the IIIF image service for the thumbnail of W22084, it's on https://iiif.bdrc.io/bdr:W22084::thumbnail/ so that you can then query for a specific size (for thumbnail or for full display) using the IIIF image request parameters. For instance on BUDA we use !2000,195 as the size parameter, so that the image returned is less than 2000px wide and less than 195px high, as in

https://iiif.bdrc.io/bdr:W8CZ40::thumbnail/full/!2000,195/0/default.dflt

Note that for the purpose of this specific task, it's best to use the non-standard dflt format that I've implemented. So you can use the same endpoint for the image preview and the thumbnail in the search, at the same or different sizes.
