Chris you replied to my post and gave me this block of code. I have a question about it. Anyone else may answer to ;-)

while(list($key,$val) = each($chk)) {
echo "<IMG SRC='$img[$key]'>\n";
}

What do I assign $key to?
I'm assuming $val is assigned to the value I want the images to appear for (the "on" value)

Thanks for your help.

The only think you need to pass the while statement is a valid array (in this case called $chk).

The statement: while(list($key, $val)=each($chk)) -- will go through each item in the array and assign the key name to $key and the value of that key to $val.

Thus, if you had an array like this:
$chk(0) = "Test 1"
$chk(1) = "Test 2"

Then $key would be "0" and $val would be "Test 1" on the first iteration of the loop, then $key would be "1" and $val would be "Test 2" on the second.

Hope this makes sense. 🙂
