I would just check out web development sites, sitepoint may have some good tutorials, and also webmonkey.com. I started designing sites through these kind of tutorials. But for your jpeg files, most people usually store their webpages in a home directory, and then use a subdirectory (sometimes labeled 'images') to store all their pictures. E.g.--
http://www.yoursite.com/images/me.jpg. That helps keep your home directory from overcrowding. Hope this helps.
