Frank,
I guess I should have worded the orginal question better, I didn't mean to say
HTML only, but I think client side only would have been better worded. I
realize that the current function isn't ASP. I should have been more clear, my
bad.
But your solution interest me. So you're saying that I put the image and the
function in a separate image.htm file, make that image.htm file the "scr" for
the iFrame and reference the Imagezoom() function in the image.htm from my
default.htm file? (assuming that the iframe is in the default.htm) That would
be cool if that what you mean. I'll have to go try it.
Thanks,
jt
