Tip (Formally warning) for people who download images from Tumblr ;)
Replacing _1280.png or _1280.jpg in the image tumblr URL with _raw.png or _raw.jpg manually gives you the highest quality variation.
_raw.png/_raw.jpg always stores the highest quality version available, even if the image itself is lower resolution. With lower resolutions the file should still be identical to raw, but to help people uploading better quality versions, and to make sure you are uploading the best version, always ensure that the image's URL/filename ends with this.
