Hi all
I'm displaying some quite large (6+ megapixels) images using CSS
background-image, and sometimes want to swap one for another. If I just
change the CSS property, there is a noticeable flicker as the first
image is removed, then the second image is loaded and displayed. I want
to avoid this.
My current approach is to create a second element behind the first, load
the new image in it, wait for a while, then remove the first element.
This works okay but it's a total guess how long "a while" should be -
500ms seems to be a good amount on my machine with these particular
images. So how can I detect (with privileged code if necessary) when the
second image is ready to be displayed?
