passing variables to javascript

sol01

I have a pop up script that is supposed to pop up the big image from the random image display script. I am using the following script located below <head> under <script>

function pop(){
EzPopUpWindow = window.open("http://www.mywebsite.com/pop.php?img=$first[$a]","Image1","left=100,top=100,screenX=100,screenY=100,width=400,height=400,");
}

--NOTICE I am trying to pass variable ($first[$a]) to the above script--

Then at my url I have this:

print "<a href='javascript:pop()'><img border='0' src='pics/$first[$a]'></a><br><br>";

Unfortunantly once the page has been loaded there is no way I can see of getting the variable to the script at the top of my page. Any ideas?

"Unfortunantly once the page has been loaded there is no way I can see of getting the variable to the script at the top of my page. "

That's a true statement.

Did you mean to set the image before displaying the first page?

...pop.php?img=<?php echo $first[$a] ?>","Image1...

Once the page has been sent to the browser, the php has completed running and is gone.

No unfortunately because the guts of this java script is contained in the top part of the page. It is then loaded first.

I few ideas I had were to create a file with the image name and then the pop up window would call the image from the file. However this is not conducive as it opens security risks as well as a bigger load on the server. Not to mention the file locking mechanism, it wont do well with more then one user accessing it at once.

Another idea would be to run it off a mysql table. I however don't see this as altogether practical.

Anyone have any better ideas for a work around??
