Hello. I am trying to do an ImageMap . I am using polygon selection. Do you know if there is a software that can select an area (maybe by color or by magic wand) to find the coordinates? Polygon selection is not the best solution.

Image map coordinates
The difficulty in finding the coords of the polygon vertices (on an image) is one of the reasons I use Visio. When you save as a web page it outputs the polygon statements, with the coordinates for you in the HTML file (that match the image in the PNG file).
If your starting point is nothing but an image one technique (in Visio or similar programs) is to overlay 'invisible' polygon shapes - that then generate the poly statements with the coordinates.
