adimpro package : R does not seem to find my ImageMagick installation

Dear list, (sorry if I post to the wrong place...), Though having spent some time on it, I cannot find an answer by myself to the following behaviour of the read.image function (adimpro package) : I'm running R.2.6.2 on Windows XP. The home directory is C:\Program files\R\R-2.6.2 Version 0.4.4 of adimpro is loaded. ImageMagick 6.3.0 is installed, its directory is C:\Program files\ImageMagick-6.3.0-Q16 When using function read.image in adimpro, extensions"tif", "tiff", "png" .. and so on are not recognized, as seems to say the following error message :
Error in read.image(file = "JFtiff.tiff") : cannot find JFtiff.ppm
In my understanding, this means that adimpro behaves as if ImageMagick was not installed, as the manual says :
If ImageMagick is not available only "pgm", "ppm" and "pnm" formats can be processed
What am I misunderstanding or doing wrong ? (perhaps wrong location of ImageMagick or wrong version...?)
Is it (or its bin directory, if it has one) in your PATH? Being installed is not enough ....
