Yes, that's fine for images like that, that's several GB in size, but there's a cut off point where tiling becomes less efficient and slower than just downloadi

Yes, that's fine for images like that, that's several GB in size, but there's a cut off point where tiling becomes less efficient and slower than just downloading the whole image in one request, I'd guess it's around 1/2MB, which a lot of images on this art site are. Even if the actual efficiency is no where near that, a 1080p jpg fits in that so it's not like people would want the IIIF functionality on images that small anyway.
