Really interesting project.
 (I would remove the empty div line 3 column 128 as it doesn't seem to be
useful and so that there is no warning with html tidy.)

 I will have a look through as soon as I can.
 I have a help page too there <http://danzcontrib2.free.fr/en/captures.php> with
the issues I  encountered. Some of them may be added to your page.
 As for flash, I will try to write an article. Have a look at these two pages
to see if some of the content can be used:
<http://danzcontrib2.free.fr/en/exemple20.php>
<http://danzcontrib2.free.fr/en/swfrip.php>
 You can contact me there so that I have an address to send the article or
have a password to write/edit the page.
