Maybe I'm unclear about what you are doing here. When I first  read 
this, before going to the page, I thought maybe you were using 
javascript or java to plot values directly by the browser, but after 
looking at the page and reading your post more carefully, are you just 
talking about inserting the telemetry graph image within your own web 
page? If so, that enabling capability has been a design goal of findU 
since the beginning. Cgi's like plot, breadcrumb, temp, rain, wind, 
baro, tele and tele1, among others, return a png image for the purpose 
of embedding it within a user's own web page (though many of these are 
used more by findU's pages like find.cgi and wxpage.cgi). Many people 
take advantage of this capability now, I enjoy going through the 
referrer log of findU looking at the innovative ways people are using 
its cgis.

If you embed the telemetry  cgi within a web page's IMG tag:

<IMG src="http://www.findu.com/cgi-bin/tele1.cgi?call=n7rig-6&last=240">

it will appear on your web page. Is this what you are talking about, or 
is there something I'm missing?
