//		SUMMARY		
//		This script queries all nodes of type "imagePlane" in the scene and toggles their visibility. 
//		
//		INSTALLATION:
//		Place this file into your scripts directory. 
//			
//			For Windows your path should most likely be...
//			"C:\Documents and Settings\*user*\My Documents\maya\7.0\scripts\LFtoggleImagePlane.mel"
//
//			For the Mac your path should most likely be...
//			(Not sure what the mac scripts directory is, please let me know if you know this). 	
//		
//		PLEASE NOTE: 
//		This script does not delete imageplanes, it only toggles the visibility (turns them on or off). 
//		
//		USAGE: 
//		Either source the script (type LFtoggleImagePlane) or run it from a shelf button (reccommended).
