While working on a JQuery to change image source on mouse over I found out that this does not works well for images with transparent parts in it.
People suggested on SO How to prevent Jquery mouseover event from executing on moving mouse on transperent image area? to use HTML image map to ignore transparent part.
Now, one more problem is, I have multiple non-rectangular images which have same shape i.e. they share the image map.
Now if I write code to change image source on mouseover of imagemap, how will I come to know for which image was mouse over/out called?
