Loading the website causes the images not to display. But following a link and then going back causes the images to properly load.

Reproducer:

<img src="http://hackaday.com/wp-content/uploads/2011/11/pic.jpg">

The image returns a 301 redirect:

User-Agent: Dillo/3.1.1

Dillo seems to ignore redirects on non-root requests like images:

https://github.com/dillo-browser/dillo/blob/f3103cc4b6c369da96c7de487214a9e56eca755d/src/cache.c#L1240-L1242

Also:

This predates the git history (2007), so I don't know the context at which this was done. It looks simply unfinished.

I was just looking at the old site and saw that this behaviour is described as intentional:

If Dillo requests an image and receives a response containing a redirection (i.e., pointing to a different URL), the redirection is not followed. These have a strong tendency to be advertisements.
