The Image Gallery module is an easy way for you to manage your photos.  If you don't have this installed and would like it, please contact support and we can set you up.  The cost of this is $200+gst.
 
The code you'll need (as mentioned above) to call the image gallery is:
 
{cms_module module='album' albums='1'}
 
where '1' is the unique ID number of the album.  Please note albums aren't necessarily numbered 1, 2, 3 etc in the order they are created.
