Update image on page?

    I need to update an image on a page (without reloading the page.)

    I can do it with an IFrame, but that's kinda awkward.

    xajax seems to be a possibility - only issue is it appears to use the xmlhttp transport - that suggests I'd have to encode/decode the image to get it into xml - performance issues there, I would think.

    xajax is supposed to support other mime types, but, since it uses the xmlhttpc transport, will it send an image mime correctly?

    Or, is there another way to do this?

    Anyway, I'm going to give it a shot - just wondering if anyone might have done it already.

    You can change the value of an image's src attribute using JavaScript, and the new image is automatically loaded.
    var img = document.getElementById('img1');
    img.src='http://www.domain.com/images/image2.gif';
    Code (markup):
    Don't know what the effect would be if the images were different sizes though, that might screw up page layout.

    Right.

    Just realized that (although my variant is to invoke a php script to get the image - keeps proprietary images out of webspace. And that works just fine.)

    So, I guess I'll suspend my xajax investigations for the moment.

    thanx,
