I'm IN LOVE with this Photoshop plugin. Create a website as a psd (layers for each element), get it how you want, and with a few simple clicks of the mouse Site Grinder spits out all the images, css, etc that you need. It takes half the time to build a website that it ever has before, and can even handle flash.
It's fucking amazing and i suggest anyone that can use photoshop try it out.
