Good stuff Jeff. Now, I assume you that you uploaded that Harvard pic from your HD. Thing is, it's 8Mb big and takes a while to load. I reduce mine in photoshop to no more than 200kB with little noticeable loss in quality so you may want to look at ways of doing that.
Good stuff Jeff. As Andy mentioned, the Harvard, and the Mustang, took some time to load. If you re-size your pics to no more than around 800 x 600 px, they'll be fine. If you don't have it already, then 'Irfanview' is a great editing tool, and it's free to download.
