Get the picture under the mouse pointer (ClientToDocument, GetItemAt).

Get item coordinates (GetItemCoords). Find the picture coordinates (add

GetItem().GetBorderWidth, GetItem().GetBorderHeight to the item

coordinates).

Now you have the picture, the mouse coordinates, the coordinates of the

picture's top left corner. You can find the pixel.
