Hi Daniele,

Yes: your are not in the right directory wrt guile, and this flename 'does not
exists', it does not exists in the directory your are trying to load this image, see:

	scheme@(guile-user)> (getcwd)
	$5 = "/usr/alto/projects/guile-cv/images"

In my cae, the sand.tiff is (also) in a subdir called 'lpdi':

	 (im-load "lpdi/sand.tif")
	$4 = (512 512 1 (#f32(125.0 128.0 124.0 118.0 108.0 95.0 90.0 80.0 75.0 76.0 # …)))

but if I try to load an image that does not exists, bang:

	scheme@(guile-user)> (im-load "lpdi/sa1nd.tif")
	ERROR: In procedure scm-error:
	ERROR: Not a GRAY, RGB nor an RGBA image "lpdi/sa1nd.tif"

Good you succeed at installing!
David
