I want to create a rollover that gives (just) a short flash.
Perhaps quite simple, but I don’t have a clue.
The idea:
thumbnail of an image.
The rollover is a lighter version of the same image.
When the mouse is moved over, the thumb gives a short flash
(about 0.2 sec. of the lighter image), and again shows the original thumb.
Everytime the mouse is moved over, it flashes again.

The simplest way to do this would be to make an animated GIF that
shows the first frame for whatever fraction of a second you prefer
(for example 20/100ths of a sec), then shows the second frame and
stops (no looping).
You can make this very easily using GIFbuilder, available from
Use this animated GIF as the rollover state graphic in your page, and
it should work fine.
Sorry, Keith, this won’t work. When an animated GIF is loaded by your
browser, it starts playing. This also happens when it is preloaded to
“wait in the wings” for a rollover. So your animation will start
playing before it is visible. The only way you could make this scheme
work is if you disabled the preload, but then you would have the
mighty pause between rollover and effect.

I would be happy to be wrong. I actually tried to do this, make an
image do a transition during a rollover, quite some time ago and it
didn’t work then. What I found was that my animation, which was set
to run once and never repeat, would run to its last frame before my
rollover ever happened. It seemed to me to be running itself the
instant that the image finished preloading. The call to show the
image had no bearing on the animation starting or stopping or
starting over.

Hmm. Really?
I’ve used this technique before, and I just tried it again. With the
standard Freeway rollover action settings including preload. Works
fine for me.
Is this something that behaves differently in that dark side
abomination of a browser?

Nope, it works perfectly. I wondered whether there might be a quirk
to do with playing once, but I just did a test with everything
exactly as I originally described - and it worked perfectly.
Try again! There may be some subtle difference between what we’re
doing that causes the problem, or perhaps there was a bug in the
specific browser version you happened to try?
Thanks for the feedback.
It works fine with a gif animation.
I used GIFfun from StoneWorks (Stone Design) for the 2 frame animation.
As soon the site is life, I will drop a link.
Because of the gif format, the image quality is quite poor.
It would be nice if it would also be possible with jpg or png files.
