Maybe more attention to efficiency is the answer?

The added jp2 file has the same quality as the most recent anaglyph I
uploaded but is four times smaller.
This means 4x faster and 4x less space in the archive.

This is possible by taking advantage of two well known techniques:
- resampling to change pixelsize without quality loss and
- compression without visible artifacts.
So, resized and compressed files are what we should exchange.

At present there are two limitations that may hamper the use of jp2:

1. most browsers need a plugin to view jp2 files
( for example
http://plugindoc.mozdev.org/windows-all.html#MorganJPEG2000 for
Mozilla Firefox )

2. I hope the yahoo anaglyph group forwards jp2 files.
To be safe I add a copy with renamed extention(jpg iso jp2), so you
have to name back to jp2 before viewing.

Knowing Etiennes coding dexterity I don't think the archive will be a
problem.

Of course this is only my point of view.
I hope to learn more from other members.
