how to convert text to image on the fly without image file
<p>I am doing some sort of directory in ASP.NET, in which everyone has phone numbers displayed.
I dont want harvesting on my site, so instead of writing 123-123-1234 I want it to be rendered from image.</p>

<p>another limitation is that I dont want to save any TMP image file. I want the server to send it right back to the client for redrawing. Is that something doable? via JS?</p>

<p>Thanks!</p>
