The frames were rendered with PovRay and mastered with Paint Shop Pro. They come in two sizes: Small (Outside Diam 320x240) like the ones on the first page of frames and Large (Inside Diam 320x240) like the ones on page 5. All have black (index color 0) set as the transparent color. Color depth is left at 256 (8 bit) so you can use them with your high color pictures. All but the four large ones are interleaved. The PDQ button will show you a picture listing of all patterns so you can pick the one you like quickly. There is a nice trick for using the same frame over and over for different pictures on your pages. Email me for more info. If you're not sure how to use them, again drop me a line. These frames are free, but a link would be cool.
ENJOY!
