JPEG is not the only image format that uses DCT/Huffman coding. TIFF
and PostScript can also use them.  As there is a real problem with
browsers being limited in supported formats, I won't check the details 
of TIFF to make sure that you can sensibly mix DCT and alpha, or the the 
latest PostScript specification, to make sure that the alpha features 
can be exposed in EPS files, but there is a prima facie case for both.

(PDF can also use DCT/Huffman, but there is no equivalent of EPS.)
