Yes. Template tags will be what I mean.
I originally wanted to use a template tag within a html page to link up Nicky's Random image mod. As the include("./random.php"); wouldn't work if placed in a html page, unless an iframe was incorporated.
It solved the issue, but it got me thinking about these template tags. Since then there have been other times these tags may have come in handy.
So I'm after tutorials or good information to learn more about them.
