Re: [APML] 10 frame Rosette Mosaic

["Bobby Middleton" <bobm@koyote.com>]

Thanks Rob. It's a 84MB file at 8 bits. I've down-sized a couple of times
already <g>. I just printed a 8 x 10, but I'll play with the image some more
with final tweeks before I have any big prints made. I'd like to make a big
print of this image.
