To be precise, a way to get png that were auto-converted to jpg.I saw a tweet and uploaded it with the bookmarklet (post #3062198). The picture was a jpg and uploaded as a jpg. However, later I saw the same image on Discord, with the same filename and dimensions, but in png. Eventually I found that indeed there's a png version on Twitter - the same filename but a different extension, and :large rather than :orig, because the latter gives me an empty page. However, trying to upload it gave me a long list of errors:

I tested it with a tweet of another artist who I know usually posts in png, with the same result (and a similar list of errors).First of all, is this a known thing?
And second, can this be used to improve the bookmarklet? If the cause of those errors is found and corrected, it can let you grab the hidden png versions automatically if they exist.
Actually nevermind, they are just lossy-lossless. I should've looked more closely.
