I use an iframe on my site that I want, that no user can see where it comes from, how can I do this?

for example

<iframe src="http://www.iframe.com/result.php?frame=option" name="frame" scrolling="no" frameborder="no" align="top" class="smallfont" height = "32" width = "32">
</iframe>

so that they won't see it's from is this possible?

In a word no, you could encrypt the code but in Firefox you can just right click on view the frame only revealing the url. Of course you don't necessarily need to use an iframe ;)
