The easiest first step would be to increase the
logging level for the image
plugin. Unfortunately there seem to be a lot of

} catch (...) {

constructs in the code, so you will get only something logged if you are
lucky.
If you're unlucky you could add more logging and build the plugin jar
yourself. That way you can also add something like LOG.info("starting
downloadAttachment"); to see if the method gets called at all.
You could check http://dev.xwiki.org/xwiki/bin/view/Community/Debugging#HUsingByteman for
that btw (which doesn't require modifying the code).
