The code for the photos version of the memory game is similar to that for the polygon version. Most of the
logic is the same. But because this example demonstrates the writing of text on the canvas, the HTML
document doesnt have a form element. The code follows in Table 5-4, with comments on the lines that
are different. I also indicate where you would put in the names of the image files for your photographs.
Before looking at this second version of the memory game, think about which parts are likely to be the
same and which may be different.
