is there ANY possible way to make a blend without buying or downloading an image program?

Without a program, I don't think it is possible to make a blend. If you mean you want to make a blend without using a graphics program like GIMP or Photoshop, then there are programs whose sole function is blending. However, 2Pic (http://2pic.moor-software.com/) is probably the only one of them that is free.
