I've tried both ways. I call the function from within the <IMG SRC=....."> and
I have tried to echo
it outside of that.
Which is the best way and/or the proper way? I still cannot get it to work but
I have one more
thing to try that a gentleman just sent.
Any ideas are certainly welcome!

I'm wondering, are you trying to send the image inline with the rest of the
page, or is it response
to an img tag?
