How to load images?

[findtype]

Hi,

 

This is question about image files.  Although the octave manual (although not the printed version) says that an image file in jpg format can be read in by

     I = imread ("myimage.jpg"),

this doesn't work in the Octave 3.4.0 that I installed.  It produces the error message,

"error: imread: invalid image file: Magick++ exception: Magick: No decode delegate for this image format...." 

(The same happens also with the bmp format.) 

 

Does anyone know what I have wrong?  My thanks for any help --
