In any case, I suspected that now there might be easy computer programs to put these works of art together for us, and yep, I found a free one on the web (you can find one, too, just use Google.)
And I created two photomosaics using only my SPCA doggie photos. :-)
To best view these, click on them to enlarge, or save to your own computer and then zoom in to take a closer look. Pretty cool, huh? They would make great posters. :-)
First, a landscape, and then a cartoon. Enjoy!
