<?php 
/* 
* GENERAL INFORMATION: 
* Implementation is simple and straight forward. I offer the script 
* in two sections. The array of arrays, and the output. Both can be 
* combined and placed on the page right where they're needed, or put 
* into two sections on the page, or the arrays can be placed in a 
* separate file and included. It's up to you and will probably be 
* decided by the number of ad arrays you will include. 
*/ 
?> 

<?php 
/* 
* PART 1 - THE ARRAY OF ARRAYS 
* I have expanded this to make the script easier to negotiate 
* If you're using constant values, you can remove those parts. 
* If wanted, you could also add captions to the arrays below.

'alt' => 'Alt Text 1' // Required alternate text

<?php 
/* 
* PART 2 - THE OUTPUT 
* This is simple, simply place the link/image line where needed. 
* I included the path as a fixed part in this example 
* I added an optional container div. Image string is XHTML. 
* Note that the ?> of the last part and <?php of this part 
* can be removed if you decide to combine the two sections. 
* Also note that contstant variables like path (shown) and 
* height and width dimensions can be added below and removed 
* from the section above if that better meets your needs
