Hide image url for captcha

Rails
1

Hi-

I’m fooling around with a picture based captcha. I want to hide the
url of an image by doing something like:

<img src = “http://myserver,com?image=JHJHK”

So I want to send a request that uses a hash. That’s the easy part.
How do I generate an image stream on the server using ROR? In other
words, I don’t want to return the filename, I want to return an image
stream that is loaded from an image file in a secret database.

Thanks for any help,
Dino
