When you splice up the psd file you get a load of images and an html file. The html file produced by photoshop is junk. Put it in the bin. Open up DW with a blank page, click insert - image and put your images on the page using DW. DW won't make perfect html but it'll be a million times better than photoshop can pretend to do.
I don't understand why people think html is so hard before they have even tried. It's not rocket science. With tools like Dreamweaver, even a newbie can make a half decent page. The only thing you need to know is that photoshop can not make html. It says it can, but it's a lie.
