ImageMagick Batch Montage - imagemagick

Question

In my first trial with Cygwin, I managed a simple montage of 2 image files into a final one.
However, I would like to batch montage all .jpg files in a directory so to combine them Two by Two, and thus have like half the original number of images.
Could you help?

I generally try to avoid Windows, but you can do it something like this:
GO.BAT
DIR /B *.JPG | CSCRIPT /NOLOGO PAIRIMAGES.VBS
PAIRIMAGES.VBS
cnt=1
Do
' Read in first image name
Im1 = WScript.StdIn.ReadLine()
If WScript.StdIn.AtEndOfStream Then
Wscript.Echo "WARNING: Unpaired file left over."
Exit Do
End If
' Read in second image name
Im2 = WScript.StdIn.ReadLine()
' Work out ImageMagick command, something like:
' convert im1.jpg im2.jpg +append result1.png
cmd="convert " & Im1 & " " & Im2 & " +append " & result & cnt & ".png"
' Show user the command, for debug purposes
WScript.echo cmd
' Now execute it
Set objShell = wscript.createobject("wscript.shell")
Set oExec = objShell.Exec(cmd)
If WScript.StdIn.AtEndOfStream Then
Wscript.Echo "Done"
Exit Do
End If
cnt = cnt + 1
Loop
Sample Output
E:\>DIR /B *.JPG | CSCRIPT /NOLOGO PAIRIMAGES.VBS
convert 1.jpg 2.jpg +append 1.png
convert 3.jpg 4.jpg +append 2.png
Done
If you want to align the tops of images with dissimilar sizes, use:
convert -gravity North ...
and change North to East if you want the centres aligned and to -South if you want the bottoms aligned.
