in fact contrary to what has been said here, using psd slices is poor technique and creates useless unusable css. it either places it as a table or AP elements both of which are not the preferred way of doing things.
I know it'll hurt, but you simply must use css and steer clear of ANY program that claims to be able to do it for you.
put it this way, you've just spent hours slicing a really complicated psd. then your boss says he wants it green instead of blue? what do you do? start again and reslice all those images with green now instead of blue.
or edit a few lines in your css changing the appropriate elements from green to blue?
if anyone needs any help with this I'd be more than happy to show you the CORRECT way, just a straight cut, slice, auto div creation and bam theres your webpage does not do you or your company any professional service. it shows only one thing - that you do not understand css, and you are behind the eight ball, coding in an archaic way. you'll lose the job to someone who can actually take a psd and create a webpage from it. not just slice it.
