The only stupid question is the one that's never asked.
You might, however, find that questions like this are more suited to the
general [EMAIL PROTECTED] mailing list.

The <dtml-in> tag is certainly what you're looking for if you want to do
this in DTML. Something like the following will do what you're looking for:
<IMG SRC="star.gif" HEIGHT="15" WIDTH="15">
The <dtml-in "_.range(stars)"> ... </dtml-in> forms a loop that gets
repeated 5 times by using the python range function -- generally, anything
inside double quotes in DTML is treated as a python expression. You'll find
that the "_." notation, which accesses the global namespace, allows you to
make use of all sorts of python functions.
You would replace the <dtml-let stars="5"> with a call to your database to
find the actual number of stars.
