Another option is to exchange the images (using the JavaScript Mikey
uses) after PHP has generated the image, so that there is less lag in
between. Whatever event you use to trigger the exchange can wait on a
response from a PHP script, and that script can generate the image
before responding, so that when you exchange images on the client side,
your server-side activity is already complete.
Hope that helps.
