[RESOLVED] using ajax to know when an image is loaded

Copy linkTweet thisAlerts:

Hi there,

Well – I have just started using ajax, it’s really sweet – I mean, you can do tons of cool stuff just with response.Text… This is what I was wondering though.

Can I use AJAX to tell when an image is loaded? Like – say I have some thumbnails and a div tag that has a larger image – I can easily replace the larger divs background image with whatever I want using javascript, no AJAX needed – however I want to find out if I can figure out when the image is loaded so that first I can display a “loading image” in the div then I can show the actual image after it is transfered from the server.

Thanks

@Typhoon101Feb 22.2008 — Why use AJAX? The <IMG> tag has an attribute called lowsrc. This points to a low resolution file which is used until the high res image has downloaded.

e.g.

<img src="high-res-image.jpg" lowsrc="loading-image.gif" />
