Example 6-02x, Placing images on the canvas

Derived from ex6-02:
The support file (*.html and *.css) are as usual.
The main subtlety in the *.js file is the code
	to await the loading of an external
	image file, which might be large.
Special method (not unique) for multiple resources.
Here I am following Fulton and Fulton, p. 543.

Problem found: have to reload to post the images.
Changes: remove extra event listener and load counting device
replace obsolete window.onload
