// Function LoadImage and OpenBigImage originally written by Gregory Smith, http://underdogishere.com
// Feel free to copy, reuse, change, pilfer from, etc. as you wish!
// Note that the Javascript works only if a certain naming convention
// is followed for the images. The LoadImage function takes as
// parameters the name of the 'big' image file (without the .jpg
// extension), and the ALT value. Optionally, you can also specify
// the medium image's width and height if it's not the default of
// (in my case) 400x300. The medium image must have the same name
// as the big image, but with "_sm" added to the end. So if the big
// image is oceanview.jpg, you would pass 'oceanview' to the function,
// and the medium image must be named oceanview_sm.jpg.
// Of course, if you don't like this exact convention, you can change
// it, but the bottom line is there has to be a connection between the
// medium image's name and the big image's name so the function
// OpenBigImage can figure the one from the other.
