Need training in graphic design and html

Hi, I am looking for a course that covers basic graphic / web design principals and applies them using HTML. I am currently taking the HWG HTML H102 course (HTML 2), but I feel like I need more of a foundation in graphic design principals, and how to use HTML and images to achieve professional looking page designs. Can anyone recommend a good course, online or classroom? I'm in the Boston area. Thanks!!
