My apologies go out to all the people who tried to view the last post (polar bears!) on a mobile device. If you happen to be one of these people, let me assure you that your eyes do not need to be checked. The blurry images you were squinting at were, in fact, blurry.
Apparently there is a photo size limit on mobile devices that, once reached, downsamples the images and makes them look blurry. I fixed the issue and, now that I know, I’ll keep this in mind when putting together photoessays.
