That has always annoyed me when sites did that... I should be able to exit just by clicking anywhere off of the image or by pressing Esc.

Even though the number of people who browse without javascript enabled is generally low, I have to agree that this should be done in all cases, no matter how much of a pain it will be to have to test everything twice any time a change is made (once with and once without js enabled). Smartphones and other mobile browsers sometimes have trouble with some javascript functions, and also many people use things like the NoScript addon in Firefox that disables js by default.
