converting jpg to jp2

[JJoe]

Basically the proxy is converting all images over a certain size to jp2.
An appropriate content-type header, image/jp2, is also sent.

If I use Proxomitron to simply change all "<img*>" to "<embed*>":
IE works ok.
Opera displays the image only if it is jp2. <embed*> did not display a gif. The images displayed were sometimes useless.
Mozilla shows the image only if the extension is jp2 and <embed*> is used.
So I think this setup really only works well with IE. Unless the other browsers' behaviours can be modified.
Not sure what will happen if IE is told to obey the extension...

I'll think about a better filter but the one posted may be the best for Proxomitron's default set.
Could add a test for the proxy, tho.
BTW Sidki's set will probably sniff all this out and stop it.

How do people use this proxy without Proxomitron? Safari?
