Seems like more often than not, I've been getting the "(link) doesn't contain any images" error whenever I upload via twitter links. I've been getting it more and more over the past few days.

This has been brought up multiple times on the forum before. It's Twitter rate limiting Danbooru that causes this error.

Just Twitter being twitter.
Right click and copy image address instead to get the picture, then go to the source tab and input the webpage url and it should work and fetch the artist name and tags.
This won't fetch the commentary, so you need to either add it manually or fetch it later.
