I was trying to upload a twitter image, so I did what normally works, right click on the image > view image > use the "Post to danbooru" bookmarklet.

The image preview doesn't show, but the suggested artist and source works correctly, but when I try and actually upload it, I get this error.

There is a workaround, which is typing it out manually (danbooru.me/uploads/new?url=<url>). But this kind of defeats the purpose the bookmarklet.

I ad the same problem a few days ago.

You have new Twitter layout. I think they've enabled it for certain users, probably for testing. And I don't think you can go back.

Do you have Bookmarklet Context Menu addon? I can upload just fine if I run the bookmarklet from that menu.

Yes, I imagined it was new twitter (which is garbage, btw, why do I have to open a post to get a translation now?!). Hopefully if enough people who maintain the bookmarklet get new twitter they will be able to make it work.

The better workaround at the moment is to install an user agent type add-on, whitelist twitter, and enable an old user agent like Opera 12.something (12.02, was it?) in order to force twitter to revert to it's previous form.. The bookmarklet will work like before for the time being.

Maybe BetterTwitter can fix it? (add-on that reverts twitter to it's previous layout)

Also someone already discovered a workaround for picture links: https://cdn.discordapp.com/attachments/310432830138089472/600668672020840448/unknown.png

@Mysterious_Uploader I tried your workaround with post #3580756, but the twitter post contained multiple images, and when I manually added the source to the uploader to fetch the commentary and suggested artist, it switched the image to the first one! I only found out after the upload, as the preview still showed the actual image I wanted to upload.

The workaround may work for single-image posts, but I would be careful on albums.

Do you mean you changed the source field to "https://twitter.com/amamotan2/status/1155684841024700416" on the upload page before pressing submit?

Yes, because using the direct image source didn't provide the commentary or suggested artist.

Yeah don't do that, unless you are uploading from disk the uploader will grab the first image it finds from whatever address is in the source box (from supported sites otherwise it has to be a direct image link for it to upload it) when pressing submit even though you may have started on something else. The safest way is to fix the source after you upload the image, no one is gonna yell at you for doing that.

I also hit this issue and had mentioned it in the Issues thread (forum #158439).

In that case always use batch upload, even if you have to just upload one out of the 2/3/4 it lets you ''choose''.

Unfortunately the batch upload has the same problems as the single-image one, the suggested artist and commentary are missing, as is the source. I think the best bet is just to establish the artist independently, and add the source and commentary later.

I got a browser extension called GoodTwitter that reverses the changes. Screw new twitter.

Use the batch bookmarklet directly on the https://twitter.com/amamotan2/status/1155684841024700416 page. There's no need to open the image in a new tab to use the bookmarklet. You almost always want to use the bookmarklet directly on the html page.

There's a known issue with twitter & firefox, the bookmarklet doesn't work directly from the twitter page (like it would with a pixiv page). The suggested solution is an add-on called boomkarlet context menu, but it's also broken currently, so I can't use it.

Go to the Twitter link of the image (as above in evazion's post), copy and paste the batch link (as below) before it in the address bar, and press Enter:
/uploads/batch?url=

This should be fixed now.
