For downloading images I would rather try firefox with the extension "ImageHost Grabber", that works sooo much better than JD.
JD can be a pain in the a.. to let him get all the links, let them be checked, sort out thumbnails, etc., it simply works much better in FF with the ImageHost Grabber extension.
