@GenieTim Wonderful, thank you for testing that! This is good information. @pearcetm What do you think? Perhaps it's worth merging #2614?

What do you mean by "scaling level"? If you're just talking about zoom, this FAQ entry explains what the numbers mean: https://github.com/openseadragon/openseadragon/wiki/FAQ#what-do-the-zoom-values-mean

It depends on a number of factors. You can read the code here: https://github.com/openseadragon/openseadragon/blob/e1e0ec6b241e11baec873a024ddf6a7e59834647/src/viewport.js#L317

Are the levels in that manifest not power of 2? If so, it's probably this: https://github.com/openseadragon/openseadragon/issues/2618#issuecomment-2494384533 More discussion here: https://github.com/openseadragon/openseadragon/issues/2419 Like I mentioned in that first comment, the simplest solution...

@demiankatz Yes, I'm sure you can tackle it... thank you for being willing to! It's basically this: https://github.com/openseadragon/openseadragon/blob/595066abd14cf4a0ffec20baa046b20ae6c1974b/src/iiiftilesource.js#L145 One approach would be to filter the `sizes` array down to only...

@demiankatz Sounds great... good luck! 😄

Great, I'm glad the instructions worked well! That manifest has `sizes` that aren't power of 2, so it does seem like it is related. What happens if you remove the...

Sorry for the confusion. I just mean removing this: ``` "sizes": [ {"width":715,"height":1000}, {"width":286,"height":400}, {"width":143,"height":200}, {"width":72,"height":100} ], ``` From the JSON at https://iiif.wellcomecollection.org/image/b18035723_0003.JP2/info.json before loading it into OSD.

Okay, if that didn't fix it, then it may not be related to `sizes` after all. There might be an issue with the tiles themselves. Do they work in other...

Wow, that is a while ago! Yes, nailing down when the change happened would be great, if you don't mind! Also, I think we've strayed from the original topic of...
