Many "web designers" are great with Photoshop, but don't understand that a lot of special effects that are easy to make with Photoshop can be very time-consuming to pull off with HTML/CSS. For the record, I think the ideal situation is to sketch out your design with pencil/paper and agree on a general layout before touching any code. When dealing with clients though, unfortunately they may expect to see pixel-perfect photoshop mockups before agreeing that a design is what they want, which can complicate things.
