How Can I save PSD Files and convert them into a html file



Hello Guys/Girls. My name is Beldwin and I am new to this forum. I was wondering, would anyone here be able to re-direct me to some kind of tutorial that will show me how to design an entire website using JUST photoshop. For instance, I create a canvas 640x480..add my text and graphics...and created. I know if I add a heading graphic...a nav bar going across below the graphic and content below....photoshop makes the slices automatically VERY large. For instance, if I select just the navbar as a slice it sliced up everything for me like HUGE slices and that takes too long to load on the net. Any help would be great...thanks in advance! Get back to me a the e-mail address above.
