Send html page (with images) using sockets

Question

I am trying to implement http and am coding this using sockets. So it is a simple client-server set up where the browser queries my server for a webpage and it should be shown. The html itself is fine, but I can't get any of the images to show up! All of my messages give me a status "200 OK" for the images, so I cant understand what my problem is!
Also, is the status and header lines supposed to be shown in the browser? I didnt think so but it keeps showing up when I query a webpage.
Please help!
