Display Page - Display Html page

[syella1]

I want to display a html page like

http://mydomain.com/show.htm?file=data/dfjhf.ccc&dfdsfs=0&nav=1

something like this as the details page of a thumbnail, i do not want to save the image(html page) in the database but only save the link.
I tried creating the template for .html but it does not seem to work

May be using frames?

Thanks
