What's the best free tool for joining digital maps?

I have a number of smallish digital maps in .JPG format that I would like to
join up into one large map.

Photostitch won't do the trick as these .JPG files do not have any
overlapping area at all.

What's the easiest free (or cheap) program to do this with?

I can use RISC OS or windows or DOS software.

I'm using www.irfanview.com on Windows.

Image Arithmetic
It is free.

"Image Arithmetic provides the following functionality:

* merge images by addition, subtraction, multiplication, division and
difference,
* merge images by selecting lightest or darkest colour values,
* merge images by interlacing vertically or horizontally,
* tile images into a matrix of up to 1024×1024 images,

etc.
The last function is what you need.

With the commandline tool 'convert' option +append you can make rows.
With 'convert' -append you can make column(s).

Use BAT files to ease things up.

example:
convert s0101.bmp s0102.bmp s0103.bmp +append r1.bmp
convert s0201.bmp s0202.bmp s0203.bmp +append r2.bmp
convert s0301.bmp s0302.bmp s0303.bmp +append r3.bmp
convert r1.bmp r2.bmp r3.bmp -append d.bmp
