use the "Slice" tool, (Press K on keyboard) and then draw the boxes that you want to be the peices. when you're done, go to File->Save For Web and choose ur settings, save it, and u have an html website!
thanx nasaboy, I too was having trouble with slicing. I didnt use the slice tool, I manually sliced each image lmao and then when i uploaded it on site with dreamweaver it wouldnt show the images. Thank you so much it works now
