You can upload up to 4000 images with Maps Made Easy. Uploading multiple linear segments is hard to do well but it is possible if you have a lot of overlap at the ends of each segment. You would need at least five or six images worth of overlapping area between adjacent sections. The best thing to do would be to try it with two sections and down what scale the images by .25 in step two of the uploader. That way you can try it at minimal cost.
