[Javascript] An image loader nearly working...

[Guillaume]

Troy and Hakan,

thanks for both of you for your answers.
I do understand your comments about this version of the script.
If you don't mind looking at the very last version of the script 
<http://www.hablablow.com/devX/loadTest2/testXXX7.htm> we have built 
with Roger Roelofs
The previous version we were talking about was my missed attempt to 
bring up a simple script... I understand now where i failed... Thanks to 
the work of Roger, we came up with another solution... It is pretty 
close to the goal we want to reach but we are still facing some 
downsides: the script does not run on Ie and the loading layer does not 
fire instantly when the page is loaded...
If we could join hands on this, maybie something nice will show up.

Thank you for your interest on this.

Regards.

Guillaume.
