I have just added this information to mouse clicks and two functions to
access it:

Function `posn-object' returns the object clicked on, either an image
or a cons (string . pos), or nil if there is nothing special at the
place where you click the mouse (use posn-point to look at that).

Function `posn-object-x-y' return a cons (dx . dy) which is the pixel
coordinates relative to the top left corner of the object (image or
character) that you click on.

In addition, the mouse cursor now changes to an arrow (rather than the
text mouse cursor) when it hoovers above an image.

Finally, when you use a block cursor, images are no longer shown in
"negative" when your window cursor is a filled block cursor (only the
border of the image is highlighted now).  So clicking on an image no
longer makes it "unreadable"...

What more do you want ?
