I was looking for something that has the tools needed to do this. In fireworks for example, you draw the slices and when you export as html, it will automatically save each slice as an image. The benefit? I can modify the design again, from a small modification as in your template, if you wanted to change the button that says community to forums, you need to re-slice the image to exact size and positions. And of course with larger modifications, it ends up being more work. Also you can resize slices to suit your modifications.
Thanks though, I don't have a design that I need to slice up, I have just worked with photoshop and macromedia products and wanted to know how you guys here work with this. Seeing what alternatives there are.
