Passing an image name as an argument

[DanDare]

Hi,

I would like to be able to open a web page and pass it the name of the picture that I want displayed. For example, the current line that displays the picture reads

<td width="762" bgcolor="#FFFFFF"><img src="165_6593.jpg" alt="" name="" width="760" height="570" border="0" /></td>

Each of the images that I want to display are the same size, so all I'm concerned with is being able to change the name of the image when I call the page. For example, if the page is called www.dandare.com and I want it to display the image dan.jpg then I'd like to call it using:
www.dandare.com?dan.jpg

dan.jpg would then be substituted for "165_6593.jpg"

This is probably easy, but I did my IT degree in 1990 when DOS was king!

Thanks in advance...

put this at the bottom of your html page

<script>
window.onload = setImage();
function setImage() {
var theimg = document.getElementById("img1");
var winloc = window.location.href;
var qstring = winloc.split("?")[1];
var qimg = qstring.split("=");
if (qimg[0]=="img") { theimg.src = qimg[1]; }
}
</script>
 

then try it out like this

http://www.wherever.com/whatever.htm?img=dan.jpg

or www.wherever.com?img=dan.jpg
