9/11 photos

Going to National Archives

I am planning to go to the National Archives in D.C. (actually the branch in College Park, Maryland) to look at this http://arcweb.archives.gov/arc/arch_results_detail.jsp?&pg=52&si=0&nh=65&st=b

Do you guys think it will be worth it? It ostensibly has over 1,400 images. Has anyone else gone to see if there is anything of value in terms of new photographs, especially of damage to wtc 7? I don't want to waste my time and money if anyone can convince me it won't be a fruitful search. It does talk about the photos being of the "aftermath", but I don't know if that means it has pictures from the day or not. Anyway, any recommendations would be appreciated.

Thanks!
