Cross Browser image transitions

Dan

Hi,

I was wondering if anyone could come up with a cross browser image
transition that I could use... I have already made one that works in IE
but i know it doesn't work in Mozilla Firefox.

Below is the script I have made, there is only one error with it
(besides compatabilty), the fact that you can make the images
transition even when there is already a transition occuring, I have
tried to compensate for this, but it doesn't work... if someone could
help me with this aswell it would be appreciated.

<html>
<head>
<title>Image Transitions</title>

<SCRIPT language="JavaScript">
var imgtran = "blendTrans(duration=5)";
var urla=new Array("Raptor.jpg","Aurora.jpg");
var trana=new Array("","");
var disa=new Array("Red Image","Blue Image")

function tran(imgtran) {

if(imgtran == ""){
var imgtran = "blendTrans(duration=5)";
}

var imgname = document.getElementById("img").name;

if(imgname == "blue"){
oDiv.style.filter=imgtran;
// Make sure the filter is not playing.
// This is the part of the script that does not work
if (oDiv.filters[0].status != 2) {
oDiv.filters[0].apply();
document.getElementById("img").bgColor = "#FF0000";
document.getElementById("img").name = "red";
oDiv.filters[0].play();
}
}
if(imgname == "red"){
oDiv.style.filter=imgtran;
// Make sure the filter is not playing.
// This is the part of the script that does not work
if (oDiv.filters[0].status != 2) {
oDiv.filters[0].apply();
document.getElementById("img").bgColor = "#0000FF";
document.getElementById("img").name = "blue";
oDiv.filters[0].play();
}
}
}
</SCRIPT>

I believe that IE and old WebTV were about the only browsers that had
built in transistions. IE has several filters, but these, for the most
part, are not supported by other browsers. You might find some image
transition effect that you like at http://www.dynamicdrive.com that is
based on script written to work on most common browsers.

However the best way to do for this sort of thing is to write the page
in SMIL 2. SMIL is an XML language that is designed for media
presentations and has all sorts of built in transitions, fades, etc.,
and everything can be timed precisely. Most browsers do not support W3C
SMIL 2 yet. However the recent Real players have nearly complete
support of SMIL built in. Thus if you have the Real player, it does not
matter what browser you have on your computer. I have a SMIL demo page
that illustrates some motion effects, transitions, fades, etc using
images, videos, and music. SMIL really is a very powerful language for
media. Go to http://www.cwdjr.info/media/playersRoot.php and select the
link REAL(SMIL) at the top of the page if you have a recent Real
player.

Of course when you use elaborate media effects, you can not expect
everyone to see them. The viewer may not have a needed player
installed, they may have javascript turned off, etc. Thus you need to
write the code so that the page degrades gracefully if something is
missing on the viewing browser.
