In case anyone else needs this right now: any #IIIF image URI can be turned into an online jigsaw puzzle. https://jigex.com/NNPR
For any @BDLSS image (like our friend MS. Bodl. 264):
1. Find an image in http://digital.bodleian.ox.ac.uk
2. Find the image ID in the metadata panel
3. Use that ID to get the IIIF JPEG URL, following this syntax: https://iiif.bodleian.ox.ac.uk/iiif/image/d21e23ac-11a8-4d24-ad4d-07ad10e0ea34/full/full/0/default.jpg

You can also crop the image if you want to. This puzzle https://jigex.com/CmEq was cropped from https://digital.bodleian.ox.ac.uk/inquire/p/52f82dbc-f000-407b-b878-26e4a0885360 (MS. Ouseley Add. 171), by plugging the IIIF manifest into @bsb_muenchen's Mirador cropping tool: https://app.digitale-sammlungen.de/bookshelf/bsb00003364/view?view=ImageView&manifest=https%3A%2F%2Fiiif.bodleian.ox.ac.uk%2Fiiif%2Fmanifest%2Fc9c5dfcc-6e14-4800-a4a7-19712b5f952f.json&canvas=https%3A%2F%2Fiiif.bodleian.ox.ac.uk%2Fiiif%2Fcanvas%2F52f82dbc-f000-407b-b878-26e4a0885360.json.
I am still researching what type of Digital Bodleian image makes the best jigsaw puzzle, but you probably can't go wrong with an atlas https://digital.bodleian.ox.ac.uk/inquire/p/b0c6f4f1-744b-4387-a013-6ff5ac21db8e
Update: the carpet page from MS. Ouseley Add. 176 is pretty good. https://jigex.com/Pxa1
