The steps in design implementation?

This is a general question on web designers out there. Let’s say you’re starting a project/concept/design, how would you start implementing it?
I used to start with Photoshop and slice it up then import it to Dreamweaver. Lately, I would just start with DW because I hate how tables are sliced up in PS, then add pieces of images (gif, jpeg).

How do you guys do it?
