Actually, that wasn't the problem. I think the issue is that I'm trying to run the rest of my code (which is all pretty instantaneous) before the image is fully loaded.
To solve this, I put the whole rest of the code inside the callback function. That way none of it runs until the image is loaded. Since bandwidth is the most important piece of this suite, it's arguably the most logical thing to do. Anyone have comments on this? andy -----Original Message----- From: jquery-en@googlegroups.com [mailto:[EMAIL PROTECTED] On Behalf Of Herr M.

I'm not sure I get the problem (correct me if I'm wrong!), but I'll give it a go. It sounds like you're not putting the "stop timer" code in the callback for the request. In jQuery, I would do like this: var startTime = ( new Date() ).getTime(); $.get("url_to_exact_size_file.html", function(){ alert("Callback says the request took " + ( ( new Date() ).getTime() - startTime ) + " milliseconds" ); }); Hope that helps! /Anders On 23 Aug, 23:37, "Andy Matthews" <[EMAIL PROTECTED]> wrote: > I think some people might have missed my problem as mixed in with the > rest of my post so I'm going to split it out. > > I'm having trouble with the bandwidth portion of my code.
