in reply to Recursive image processing (with ImageMagic)

Irfanview should do what you want already.

i_view32.exe c:\*.png /gray /convert=d:\temp\*.png

I don't see an obvious option for recursive directories, but the directory diving can be done with a very small script that makes the calls to convert everything in the directory.

    I know Irfanview well, but have never tried it on the command line. Within the Windows UI, attempting to wildcard the folders chokes the app. I assume there's a hardcoded practical batch limit in there somewhere. Better to use something like Perl to discover the PNG files one-on-one, process and move on to the next.
