Web Browser PSD's Web page mock ups in a PDF or printed document always look so much better wrapped up in a browser window. And of course, it helps the client visualise how the final product will look. I don't put every mock up in a browser, sometimes its easier and more worthwhile to set the preview up in a quick HTML file, but I do use browser mock ups often enough to warrant having at least one
