I regularly slice web designs provided in PSD format. As a site-builder, I don't need to create graphics—I only rearrange the layers, hide ones and show others, pick colors, widths, heights, and so on. What tools are there to do that job?
I know Adobe Photoshop, but it's a very expensive tool for a site-builder who doesn't want to draw and have the many fancy features, but open the PSD dependably (GIMP mostly fails at this point unfortunately), and slice it to build the website template. There are lots of image viewers can open PSD files, I know, but those application are not what I'm looking for—I haven't found one allows me to deal with layers.
