Anyway, here's the JPEG FAQ explaining why using JPEG for alpha wouldn't be a good idea even if it was supported: http://www.faqs.org/faqs/jpeg-faq/part1/section-12.html http://www.faqs.org/faqs/jpeg-faq/part1/section-12.html
- robin_reala 16y agoYep, but that article goes on to say: The only real solution is to combine lossy JPEG storage of the image with lossless storage of a transparency mask using some other algorithm. Which is exactly what the OP has done.
