Random method 1

[tseh]

I have a series of picture that I want to show. One random picture per session. I don't quite understand the random method provided in JavaScript. Could some one explain or suggest another solution?<br>
<br>
Thanks

&nbsp;&nbsp;&nbsp;&nbsp;The JavaScript <FONT FACE=monospace>math.random()</font> function simply generates a random decimal number between 0 & 1, inclusive. To change this to an integer value to be used in selecting a random picture, simply multiply the number generated by the number of pictures you have, then convert to integer...then you can call <FONT FACE=monospace>document.</font>image_name<FONT FACE=monospace>.src=eval(randomNumber)</font><br>&nbsp;&nbsp;&nbsp;&nbsp;This method will change the source of the first picture on your page to whatever location is assigned to the variable whose name matches the value of <FONT FACE=monospace>randomNumber</font><br><br>Ex:<br><br><FONT FACE=monospace>&lt;script language=JavaScript&gt;&lt;!--;<br>var randomNumber=math.random()*5;<br><br>var 1=&quot;<A HREF="
