Can't help with the site, but if you want to try to draw your own, try this even if you suck!
Make your outlines in chalk, pencil, or "sharpie" marker. The marker is best 'cause it doesn't indent when you draw.
Hold the drawing marker way up toward the top, or "the end the cap is on" and pull the pen toward yourself, while making the sides and point of the flames. Then connect the "sides" with curved lines and half-circles at different distances.
Paint airbrush or even do this on covering, then cut out the flames with an exacto knife when you've drawn them.
Try it, it's fun, AND it will be your own interpertation of "flames".
