Embedded images from Dropbox don't work

If I try to link to my images hosted on Dropbox, then in place of the image in my post I get an "Image error" message. Here is an example:



I think this is because Dropbox links are https, and Phorum doesn't understand https. If I change the https: to http: then I get this instead:



Is there a workaround? Can anything be done to allow images on Dropbox to work in these forums? I don't want to have to open another photo sharing account just for these forums.

Thanks - DC

Phorum unterstands https fine, but when you click on the link to such a JPEG file, you don't get a picture file back, but some HTML with this file embedded, instead. In other words, Dropbox violates the Internet protocol and there's not much what one can do about it.

Actually no, there is no rule that says a URI must return a particular type of content. The content type is specified in the return HTTP header. The content should then be displayed by a web client, whether it is HTML, jpg or whatever. Obviously Dropbox works fine with internet browsers, and Dropbox is not violating any internet protocol

It's a limitation of Phorum.

Hmm, strike that. I can't find a definitive statement in the HTML specs.

Either way, Dropbox are deliberately not making it easy to hotlink images, and it seems the Public folder feature has been withdrawn for new users. There is another hack that works for now: replace "www" with "dl" in the URI e.g.

http://dl.dropboxusercontent.com/s/sj0ppwuhdonc4or/example.png

Let's say it's highly unusual to send a HTML document in response to a request for a JPEG. Violation or not, they could make these links ending in .html easily.
