In doing a big of digging, it appears that Lighthouse (Google’s image serving infrastructure) is sometimes disallowing images with the =s0 suffix.

For example, the following two photos are up for review on the same wayspot:



Typically, the zoom feature is simply the same URL with =s0 appended (=s0 means original size, while something like =s1024 would scale to 1024 pixels along the largest axis).

When using the first image with the =s0 suffix, I am seeing a 403 error:

As I am writing this, the preview shows the following:

I have no idea if this is a “me problem” or more general.

I can load the image with =s1600 but not =s1601 (403 again). But that is still smaller than the full size of the other image (2448 × 3264). So I don’t think it is a configured limit issue?
