Combining images that have a reference on them

I need to combine multiple images of a person's face into one. The face has a reference triangle placed on it. The triangle is there to orient/resize the images to one another. The images will all be the same resolution. I was wondering how I could implement this.

• Find the point of intersection
• Rotate if necessary imrotate
• Put them together. This thread might be good for that: http://www.mathworks.com/matlabcentral/answers/10101-matrix-image-merging
