Alas, seems Mssr Boutell's site is no more. Did find a zip for it on "PHP.net" ... which contains a series of folders, and no idea what goes where! (I have "C:/php") It also seems that you need to run dmake or sudo (?) to install (and call which file?)... and then you need to load a perl interface to it ... and source and install files to process jpeg files

So looks like I'm back to Imager!
