I may be missing something ...
what is the advantage of using tooltips over simply setting a custom 
property ?

if the cWhatDoYouFancy of it is true then do WHAT YOU FANCY

This leaves the tooltips available (should you want) for their normal 
use, and each image can have multiple of these as needed

 if the cDragAndDroppable of it is true then do DRAG IT
 if the cMultiColoured of it is true then do ConvertToGreyScale
 ...
