Are there any tools for (in order of preference) Mac, Linux, or Windows to extract images per layer set from a PSD file, without using Photoshop? I had a web designer send me a PSD file containing multiple pages, and each page is apparently in a layer set, and GIMP cannot handle these -- it can't understand layer groupings.
A command line tool, a rinky-dink Windows tool...anything will work (of course, free is preferable), so long as it does not leave watermarks or anything of the sort, and works well.
