Software tool "Image Cut" is used to split image into rectangular segments, which are ideally fit with each other. Split operation becomes very easy. You can select parts of an image arbitrarily, not only as a simple grid through all image area. One that you need is to place cutting lines and "Image Cut" will do all other work for you. It will save each pointed segment in BMP, JPEG, GIF, PNG or TIF formats and generate merged image as web page.
