If you want to change the images  you need to open the XML file (load/load.xml)

You will see that the XML code looks like this:
  <image>
  	 <small_bimage_path>load/smallimage/1.jpg</small_bimage_path>
	 <big_bimage_path>load/bigimage/1.jpg</big_bimage_path>
	 <description><![CDATA[ Your text here ]]></description>
  </image>
 
  <small_bimage_path>load/smallimage/1.jpg</small_bimage_path>  = the small image  file location -- IMPORTANT -- the image width must be  145 px   and the image height must be 97 px

  <big_bimage_path>load/bigimage/1.jpg</big_bimage_path>  = the big image  file location -- IMPORTANT -- use high quality images

 <description><![CDATA[ Your text here ]]></description> =  your description, this is html formated text so you can change the color or size, add links, etc.
