Image viewer
A little JavaScript program so that your visitors can view all of your images? Nothing easier. Take a look at this:
To obtain this result, first copy this code in the header of your page:
<SCRIPT LANGUAGE="JavaScript">
var rotate_delay = 5000;
current = 0;
function next() {
if (document.slideform.slide[current+1]) {
document.images.show.src = document.slideform.slide[current+1].value;
document.slideform.slide.selectedIndex = ++current;
}
else first();
}
function previous() {
if (current-1 >= 0) {
document.images.show.src = document.slideform.slide[current-1].value;
document.slideform.slide.selectedIndex = --current;
}
else last();
}
function first() {
current = 0;
document.images.show.src = document.slideform.slide[0].value;
document.slideform.slide.selectedIndex = 0;
}
function last() {
current = document.slideform.slide.length-1;
document.images.show.src = document.slideform.slide[current].value;
document.slideform.slide.selectedIndex = current;
}
function ap(text) {
document.slideform.slidebutton.value = (text == "Stop") ? "Start" : "Stop";
rotate();
}
function change() {
current = document.slideform.slide.selectedIndex;
document.images.show.src = document.slideform.slide[current].value;
}
function rotate() {
if (document.slideform.slidebutton.value == "Stop") {
current = (current == document.slideform.slide.length-1) ? 0 : current+1;
document.images.show.src = document.slideform.slide[current].value;
document.slideform.slide.selectedIndex = current;
window.setTimeout("rotate()", rotate_delay);
}
}
// End -->
</script>
Simply configure two parameters in this script:
rotate_delay indicates the time delay between the display of two images for an automatic sequence (in milliseconds), while
current indicates the number of the starting image.
0 corresponds to the first image in your list.
Next, create your viewer:
<form name=slideform>
<table cellspacing=1 cellpadding=4 bgcolor="#000000">
<tr>
<td align=center bgcolor="white">
<b>Image Slideshow</b>
</td>
</tr>
<tr>
<td align=center bgcolor="white" width=200 height=150>
<img src="my_picture1.jpg" name="show">
</td>
</tr>
<tr>
<td align=center bgcolor="#C0C0C0">
<select name="slide" onChange="change();">
<option value="my_picture1.jpg" selected>First picture's legend
<option value="my_picture2.jpg">Second picture's legend
<option value="my_picture3.jpg">Third picture's legend
<option value="my_picture4.jpg">Fourth picture's legend
</select>
</td>
</tr>
<tr>
<td align=center bgcolor="#C0C0C0">
<input type=button onClick="first();" value="|<<" title="Beginning">
<input type=button onClick="previous();" value="<<" title="Previous">
<input type=button name="slidebutton" onClick="ap(this.value);" value="Start" title="AutoPlay">
<input type=button onClick="next();" value=">>" title="Next">
<input type=button onClick="last();" value=">>|" title="End">
</td>
</tr>
</table>
</form>
Simply replace the
my_picture1.jpg,
my_picture2.jpgetc. with the names of your images, then fill in the legend for each of these images. That's it!
