Image search path?

[Alasdair McAndrew]

I understand that "addpath" can be set up in .octaverc to add directories of commands to Octave.  But how do I search for images?

I've tried using "IMAGE_PATH" in my .octaverc, and indeed when I call "dump_prefs()" the paths are all listed.  But "imread" from the image package can't find images in these directories.

How can I add directories that are searchable by imread?

Thanks,

Alasdair
