Subject: [PATCH] new function comicpress_display_comic_image() which you can
 pass a string "archive,rss,mini,comic" whatever order you want to try first,
 as well as can pass boolean use thumbnail which will check if the post has a
 thumbnail image if so use that and bypass the other thumbs echo
 comicpress_display_comic_image("rss,comic", true); is a valid usage, will
 check if there's a thumbnail for the post and use that, otherwise check the
 rss directory for an image, if can't find that, default to the comic
 directory.
