Tumblr is doing a stupid here. I’ve been trying to work out why my photos look funny in the dashboard view - for a start, despite using a URL, the photo being shown is actually held by Tumblr. I didn’t think this was the case.
More importantly, for some reason the image tumblr has created is being ever-so-slightly upscaled (from 498x750 to 500x753) for display, which is why it looks bad.
Tumblr, please make this stop. This is *just* like the stupid flickr did when they changed the photo page to the ‘liquid’ layout, and had images being up/down-scaled by a few percent in-browser.
It’s bad, bad, bad. Make it stop.
