Just out of curiosity, why use php for something as simple as image
rotation? Why not just use Javascript, or do you expect that Javascript will
not be available? Just wondering. Either way, just check the date and use
it as a control to select which image to display. Another option would be to
add a cookie which expires in a day, and just store the imagepath in the coo
kie. If the cookie exists, show that image, otherwise, make a new cookie
and store that image. There are lots of options, but really, it's rather
stupid to be scanning words to begin with, since most people seem to have an
attention span of less than four seconds, especially when online, it's
always best for a page to be as fast as possible, and I expect your poet
friend will lose visitors if he continues on insisting to use scanned poems,
rather than just words. People online aren't known for their patients.
