There is really nothing we can do here because we do not store these images locally and all we do is to reference back to the original image that is specified on the RSS feed. In this case, the URL used in the rss feed is,

http://www.haufe.de/image/loom-320846-1.jpg?width=330&digest=pdBMA7d34KcPm3pKbqd2nu0KhZoCaJDbPzL2+oH1zGA=

However, the above url seems like it is preventing hotlinking. If you access http://www.haufe.de/image/loom-320846-1.jpg , it works fine. There is nothing we can do here because this is the issue with your feed source.

We cannot modify our feed importer simply because of your feed source as there are some urls that uses query string to inject specific settings.
