Or you might want to try
chmod 644 ~/tortuga/notredame*.jpg
seeing as how that won't make files in the root directory (which probably aren't there anyway) executable. A really safe bet is to run
chmod -R 755 *
'cause that will make all files readable *and* all directories available for viewing. But it will fuck all the permissions to everything you have. So I wouldn't do it.
Anyway, here's his notredame3.jpg, which I got to a few hours ago but didn't post for some dumb reason.
