Looks like Magarena has been blocked from downloading images.

See issue #667 for my travails.

But ultimately it looks like they have blocked Magarena. I resolved it by pretending to be a browser using the following :-

-Dhttp.agent="Mozilla/5.0 (Macintosh; U; Intel Mac OS X 10.4; en-US; rv:1.9.2.2) Gecko/20100316 Firefox/3.6.2"

Might not be as bad as I first thought. It looks like they might be blocking the default generic http.agent (https://groups.google.com/forum/#!msg/comp.lang.java/aSPAJO05LIU/ushhUIQQ-ogJ) which is something like "java <version>" which would appear for any java application so it makes sense why they might block that. I found that setting -Dhttp.agent="Magarena 1.70" to work as well. It would be good manners anyway to identify Magarena as the http.agent.
