I've been reading about the new .BPG (Better Portable Graphics) file format, which has several advantages over .JPG, most notably a smaller file size, but WITHOUT the loss of quality.

With this in mind, I wondered how I could get in to work on CODEF, and with the addition of a small decoder script (about 55kb), it can!!
Nothing very exciting, as you can see here...
