FWIW, those repeated call to document.getElementsByTagName are very
inefficient, and there's no reason for the closure over the function.
(Also, you missed off the indexing into the array :-)

A faster method in terms of execution speed, which is also less likely to
encounter problems from memory leaks, is to get all the images outside the
loop and add a function reference:

function cancelMenu() {
   return false;
}

window.onload = function() {
   var allImages = document.getElementsByTagName("img");
   for (var i = 0; i < allImages.length; i++) {
      allImages[i].oncontextmenu = cancelMenu;
   }
}

(Note that the above clobbers any other onload handlers, so adapt it
accordingly for your circumstances.)

HTH,

Nick.
