John,
If I understand you correctly, you wish to reload just an image on a page
every few (perhaps 30) seconds? If so, your best bet is to use JavaScript.
SetInterval will allow you to create a block of code that execute every x
milliseconds.
Example:
setInterval('reloadImage()', 30000); // 30 seconds
Then, the reloadImage should replace the image thusly:
function reloadImage()
{
img = document.getElementById('theimage');
img.src = '/path/to/the/image/theimage.jpg?' + Math.random();
}
The Math.random() appended to the end of the image filename ensure that the
browser will reload the image.
HTH,
