Hi Zoltan,
ok, let's break the problem down slightly.
a) you need a netWebSource procedure to hold the image.
Inside this, use the .CreateImage method to create the HTML for the image, or just hard-code the <img> tag yourself.
This is the bit where you'll find the image name from your data file etc.
b) make sure this netWebSource has the
Generate Ajax Div ticked on, and fill in a timer.
c) "embed" this procedure on another page, using the
<!-- Net:procedurename -->
syntax.
Cheers
Bruce
