That's what I suspected but yes, all the 'back in JS' stuff does indeed happen in the onSuccess. (I also tried onComplete, but got the same result.) I think the problem may be that the div, inevitably, is replaced right at the end of the process (at the end of the onSuccess), and only then is the offending <img> tag unleashed, calling either the image itself or my little php script... but then I'd have thought preloading it might help, but it doesn’t seem to. I also tried loading it via a php exec() call to the image script in advance of returning the output string to JS, but that didn’t help. What also convinces me that you're right about the A in AJAX is that when, for testing, I put a sleep(5) in the image script - which should hold it up by a whole 5 seconds - the div is still replaced immediately. When I first load the page (which also calls this script), I get a broken image icon where the image should have been, replaced after 5 seconds by the image, but when the div is replaced by the ajax call that doesn’t happen - I just get no change of image as before. It really would be /so/ nice if I could get this working! It's for a password-protected CMS, so the world at large will never get the benefit, and I could simply reload the whole page instead of just the one div, but it's become a challenge! -- Cheers...
