I am a graphical Neanderthal, this simple tool helps me make fancy 'glass' buttons - easy to slice and use for sliding doors as well
Pretty much explains itself, this site makes glassy buttons easy, just provide the colors and dimensions (text if you want) and you are done. This is a nice tool to use as you can just make one image without text and slice the end off for use with sliding doors - that way you don't have to make 500 images for your site, just a few depending on verticle sizes/colors. The tool also provides you with rollover changes, pretty slick. The downloadable .zip includes .png, .jpg and .gif files.
