Subject: On-line drawing tool for phpBB system ?

I am looking for a solution to add on-line drawing tool 
to a phpBB discussion board. 

The idea would be that the users can draw their own 
simple drawings with the tool and attach them easily 
as images in the discussion. The idea is to easily 
add small drawings to the postings. 

The drawign tool should be easy to use and learn. 
It should be easily integrate to the phpBB system. 
It should work in the users web browser without 
needing lots of fancy plug-ins and such...  
Should work with as many browsers as possible 
(preferably at least IE, Mozilla Firefox, Opera, 
operating system independent, so that Windows and Linux 
users can use it). 
The image drawn with the tool should be visible 
on the discussion as standard images without 
need for any plug-ins for the discussion board users. 

The solution could be for example some Java 
applet or some Javascrip DHTML hack. 
The drawing program style could be avector 
drawing tool (for example SVG based) or 
bitmap image editing program. 
The drawing coudl be stored in vector or 
bitmap format to server... but the end 
result should be that the drawing are 
viewagle as normal graphics pictures 
on the phpBB discussion (gif, jpeg or png).
There is no need for full selection of colors, 
drawing with fidex 16 olors woudl be well OK. 
The program shoudl support a library of 
ready made graphics symbols that can be used 
as part of drawing (like Dia graphics libraries). 
The symbols would include electronics / electrical 
symbols etc.. (can be built in or if symbols can be 
easily put to system that is OK as well). 

I have looked a little bit, but I have not found 
anythin that would fuufill all my needs nicely.

Solution would be preferably free open source 
(some inexpensive commercial solution would also be considered). 

I am ready to do some server side coding to make the 
system work if anyone knows parts that could make 
such system.

One idea that comes to my mind is to have just  
a simple bitmap editor program. The user gets 
when he/she starts a graphics image that contains 
the needed symbol plus marked are where to write the image. 
When user saves the drawing, the server gets the full edited 
image with everything, and cuts the part inside drawign area 
that is then saved as the drawn picture (the symbol library 
etc... parts are cut out on final result). 

Any ideas are wellcome.
