Merging multiple images (not Panorama)

[ashf]

What is the better way to merge multiple images?
Like image scanned separately.
Merging both vertically & horizontally unlike panoramas that is merged only horizontally.

I know that is just a schematic but you will need more overlap on the horizontal and there isn't enough on the top set of three either.

Specialized software is going to get you better results but hey, give it try. I would just load up the 9 images and see what happens, the key is taking more than you think are needed, maybe four high by 5 wide instead of the 12 or 9.

By using Panorama?
I need them to be aligned automatically but manually.

Specialized software that's affordable is also welcome.

Yes, I have neither the patience nor the eyesight to do that by hand anymore.

I have to add a caveat in that if there are large blank areas, like blue sky, then all bets are off.

Thank you.
