I was editing a post with a primary intent to include pictures in the post that had been linked to by a low rep user. (The post appears to have been deleted). Normally this process is very easy - copy the URL, and paste it in the "From the Web" tab of the image uploader. However, it rejected this Dropbox image with the error message:

"Failed to upload image; the format is not supported"

I downloaded the pictures, which worked fine, but wasn't near as convenient.

This was the URL for one of the Dropbox pictures. https://www.dropbox.com/s/l4mqh9ji0p4sdu7/Screen%20Shot%202012-12-15%20at%2011.20.25%20PM.png

Is this happening because it is a secure HTTP request or is there a way to mitigate this problem in the future?

It appears the imgur upload service isn't finding the embedded image, but there appears to be a somewhat simple workaround.

  • change www to dl after the https://
  • append ?dl=1 to the URI

I'm not sure if stack exchange will want to implement this systematically (or even can implement this) or if opening a ticket with imgur to better scrape a dropbox hosted image would work.


  • This no longer appears to work. The image upload simply reports invalid url. =(

  • @J.Steen Bummer - it might be time to ask a new question, but I'll check to see if there's another tweak that might work now that things have changed...

  • Forcing the right-click menu to show, and selecting "Copy image URL" (in Chrome) and using that URL works. But such a workaround. And you'd need to actually go to the dropbox image in question.
