//////////// IMAGE ROLLOVER SCRIPT //////////////
/////////////////////////////////////////////////

// This script automatically chooses a rollover image based on the original path. The rollover image must be named identical to the
// original plus the letters "mo" appended BEFORE the file-type extension (original: "file.jpg", rollover: "filemo.jpg"). These files
// must be saved in the same directory.

// Image syntax: <img src="file.jpg" id="file-id" onmouseover="imgRoll('file-id', 'over')" onmouseout="imgRoll('file-id', 'out')" />

// This script accepts all web-valid image formats.
