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.
Yeah, we’ve known about this for two or so weeks now, and site now grabs the _raw whenever possible. There are a lot of images to replace, but we plan to do so without reupload/duping.
Should check that the _raw resolutions are not supposed to be restricted, since artists may have posted full resolutions to Tumblr and relied on the downscale, the _raw resolutions may actually be purposely exclusive to patreon, behind paywalls, for physical prints or other such stuff.

Might be worth giving verified artists settings for a per-source/global max width and then either rejecting or resizing uploads that exceed it. Especially if replacements are going to be automated.
@Pone of Justice
In practice, if an artist has uploaded an image themselves, that often is considered the de-facto largest version of the image that will be allowed on the site. So the artist doesn’t have to define a size - they just upload the largest version they want publicly available.
@Derpy Whooves
Right. I’m mainly thinking of cases where the uploader isn’t the artist or where the artist might want to partially or fully opt out of having existing uploads re-fetched if they’d previously assumed Tumblr wouldn’t serve the original resolution.
It seems some _raw images only work if the beginning of the url was changed to “media.tumblr” rather than say “68.media.tumblr”. Else it would give an error. Just letting people know.

How/When does that occur? For instance, this pic >>1487127 (NSFW) posts the source using the _1280.png url rather than _raw.png. Is that intended or bug?
