The pictures aren't showing up. I wouldn't count on an autographed photo being authentic, however. most of those are autopen-signed (a machine signs it). Your letter is probably really written by the President if it was handwritten. If it was typed, it is less likely (because a secretary could type it and an autopen could sign it).

wow thats cool! just so yoou know I cant seee any of the pictures. I dont know if its just me or what but that is really awesome. Good to know that he is doing things like that which i guess he kinda should as the president but wouldnt have to
