What Params can be used to obtain the highest possible quality images (professional photographs) of observations made with the iNaturalist API?
There aren’t any specific params. The photos are available in various sizes, and the largest one is named original.jpeg. This may not exactly match the actual original, though, because iNaturalist automatically crops all photos to no larger than 2048x2048. Once you’ve got the photo ID (e.g. from GET/observations), you can use that to fetch the photo using a url of this form:
