[Dynapi-Help] Changing image source dynamically, smoothly?

[Jack C. <jac...@ne...>]

Hi,

Is there any way I can change the src of an image so that the change
occurs AFTER the new image has been loaded?
Normall I do it like this:
var pic=dynapi.functions.getImage('mypic.jpg', 100,100);
picarea=new DynLayer("", 0,0,100,100);
picarea.setHTML(pic.getHTML());

Then when I want to change picture src, i do:
pic.src='newpic.jpg';
picarea.setHTML(pic.getHTML());

However, the original picture becomes blank, then the new image slowly
appear as it is being downloaded.
Is there anyway I can let it finish loading first, then display?
I cannot preload the image at load time because the new image src URL is
input by user.
So, I want : User says change image > small delay (nothing changes on
screen) > new image appear instantly
Or, at least during the download time, keep the original image there...
I don't want it be blank.

Any input is appreciated!

Jack
