Hi I'm one of those people you can contact. The pictures need to be smaller than 200 kb, that's about 6x8 inches. Many cameras take enormous pictures, you probably have some photo editing software with your computer. This thread gives more information on creating an album and uploading pictures, there is also a link to a free program that will resize your pictures.
