I was browsing through the new JPEG code, and didn't immediately see a
way to embed comments or other arbitrary data within a JPEG. I believe
that the standard supports this; before I dig deeper, I hope someone
can give me a quick answer.
The reason I want to do this is to embed a serialized and compressed
morph (such as you'd find in a .morph.gz file) inside a JPEG that
looks like the morph. My goal is to integrate a simple drawing tool
into a Swiki that can edit a compound morph, and then generate a
JPEG to be displayed in an HTML page. If someone want to re-edit
the JPEG, the morph stored in the "arbitrary data area" is opened
in the browser plugin.
