[jQuery] how to show the loading image during image loading

[WebolizeR]

Hi;

I got an image like this <img id="myImage" src="flower.jpg" />

the src of this image will be changed by dynamically via ajax response

During AJAX response and after getting the new src of image, I need to
show the loading image instead of orjinal image.Problem is that when
new image is bigger,it gets time so loading image disappears but new
image not yet loaded...

How can I handle this?

tHanks...
