I have now been able to add my final photograph. I now need to add to my web gallery.

In Photoshop I changed the size of the image to the same as the others and saved for web and devices. I then saved in the images folder in my web gallery folder. I also saved in Thumbnails and saved in html. In Dreamweaver I added code to photos.xml and photos.js saved and opened my portfolio in Safari where I can see it worked.
