A minor flaw that cohost--as well as basically every other website that serves user-generated content--has is the thing where any image gets scaled to the size of its container, even ones that are smaller than the container. This 152x57 pixel screencap of a tumblr post probably does not need to stretched out to 630 pixels on desktop. Granted, I could use the inline image trick to force it to render actual size, but that's frankly kind of a pain.
complaint over.
