IMHO you don't need AJAX for that, becuase AJAX require XML HTTP Request to
client, you don't really need to do that in case you know how your image URL
should looks like. For example if you implementing a zooming functionality
you just need a javascrtip to select an area of the image, then you
calculate (in javascript) coordinate of rendered graph (as subsect of
original image) and just replace the image's URL inside javascript. That's
all, browser will make a request to the server and refreshes the
image.Basically
it's something like
document.getElementById('im').src='img1.jpg'
I'm sure you will find a good replacement in Prototype for "
document.getElement...".
