I'm just starting to re-use templates or general layouts for gallery pages. Thus far all of my free sites have been orginal works of art. I mess around with multiple thumb sizes a lot and the way they're layed out. I don't get inspired very often. Mostly I just sketch thumb patterns in a notebook and decide if the new design is worth the hassle and time. I've built single free sites with four different thumb sizes on a gallery page. It can become much more time-consuming than what the individual site's income potential demands. But I have lots of spare time.
