I know how to use buttons to go to the next and previous picture in
slide show, but i want to change it so when the user clicks the picture
instead of button, the script shows the next phicture.
How can i change it?
Any suggesstions?
Thanks!
<script language="JavaS cript">

var x = 1

images[4] = "images/SENNAS.jpg"
images[5] = "images/arytonsennaS.jp g"
//add additional images here as required
function backimg(){
if (x != 1){
document.image1 .src = images[x-1]
x-- }

function fwdimg(){
if (x != 5){ //Change the 5 here to your total number
document.image1 .src = images[x+1]

You may need to preload images:
<script type="text/javascript">
x = -1;
images =["ann.jpg","dave .jpg","joe.jpg" ,"gary.jpg","le e.jpg"]
function stepimg(){
if(x==images.le ngth)x=-1;
document.image1 .src =images[x++];
}
</script>
<a href="#" onClick="stepim g()">
<img src="ann.jpg" name="image1" width="120" height="150" border=0>
</a>

I don't want to be negative in this 'post', but perhaps you would you like
to revise that.

It should work, but I would preload the images.

I would consider if this would be 'expected' behavior. If the user is used
to clicking a picture to enlarge it or select it this might be annoying.
Maybe use arrows or img controls to move forward or backwards. Like you
would see in most slide show and image viewers.

Taking your modification to the existing source:
x = -1;
images = ["ann.jpg","dave .jpg","joe.jpg" ,"gary.jpg","le e.jpg"];
function stepimg()
{
if (x == images.length)
{
x = -1;
}
document.image1 .src = images[++x];
}
We now have a situation where a call to stepimg() will attempt to access
images[5], which returns undefined. You'd need to modify the condition
as: if (x == images.length - 1) in order to avoid this. I'm also not a
big fan of global variables to track the next image, I'd prefer the
images Array to "know" it's next position. So something like this would
be preferable (to me):
var images = ["ann.jpg", "dave.jpg", "joe.jpg", "gary.jpg", "lee.jpg"];
function stepimg()
{
document.images['image1'].src = images[images.nextImag e =
images.nextImag e || 0];
images.nextImag e = (images.nextIma ge + 1) % images.length;
}

Hi,
I have the following coding on a web page. It causes two pictures (pic1.jpg
and pic2.jpg)
to show, one above the other and then when one clicks on the top picture is
squeezes to
the left (as its width is reduced) to show the bottom picture. Then when the
bottom
picture is clicked the top picture expands to the right to cover the bottom
picture again.
