 +
//** Dec 7th, 08'- Script created
 +
//** February 6th, 09'- Updated to v 1.3:
 +
//1) Adds Description Panel to optionally show a textual description for each slide
 +
//2) In Auto Play mode, you can now set the number of cycles before gallery stops.
 +
//3) Inside oninit() and onslide(), keyword "this" now references the current gallery instance
 +
 +
//** May 16th, 11'- Updated to v 1.4: Adds ability to show image gallery only after all images within gallery has been loaded. Requires jQuery 1.5+
