Funnily enough I think your server was running an update of sorts just now, because my first test pic uploaded perfectly, but then the updates were constantly stalling, both here and on Try (page loads were also slow, so I’m pretty sure it was server). Perfectly fine and snappy again now.
Because I happened to experience a longer than usual loading time, I did notice a few minor quirks, but both might be quite hard to do anything about:
- Cancelling the upload doesn’t remove the inserted upload placeholder text. I can see why this might be tricky.
- GitHub doesn’t even offer a cancel option…
- If the upload is finished in the background while the smiley selector is open, my smiley will be inserted into the image link, breaking it.
- Interestingly, following those same steps in GitHub ends with no smiley being inserted. Maybe they encountered this too, and solved it.
