It's a good start to a new website.
What I do recommend though, is if your capable of editing PHP Script..
Change the logo at the top so it is centered and possibly smaller but longer width ways. Also maybe you could move the search bar into the top right hand corner.
Move the information bar about the photo underneath the main photo itself, then centre this.
Also possibly center the next/previous buttons, on my 22 Inch screen it is a pain to keep moving all the way from one side to another.
Apart from that, the pictures are of good quality
