jpeg compression is supported in eps images. Use jpeg2ps to convert the
images -- file size will only change marginally, as basically just the
file header is changed.
Other tools will put the image as bitmap into the eps file. This will
result in huge files, but it is _not_ vectorizing the image.
Those who give up essential liberties for temporary safety
deserve neither liberty nor safety. -- Benjamin Franklin
