What is the best way to go about slicing a psd, png to html / css? Special programs geared toward this? I am more a developer and novice to design aspects.
You can slice right in photoshop...save all the images to your "images" directory and go from there with whatever text editor you use. http://designm.ag/resources/converting-psd-to-html/
You don't necessarily need to use the slice tool. I find saving a backup of my Photoshop file then cropping each image out one by one works the best. I never could get to grips with slicing.
I always use the marquee & crop tools in photoshop, you can make sure everything is pixel perfect that way
