Need image files to test Octave/Matlab compatibility

[Carnë Draug]

Hi everyon

as some of you already know, I've been working on the reading and
writing of images functions for Octave. I would like if people could
send me some image files you have around for testing purposes. Weird
file formats are specially welcome. You can send them attached to a
reply, or upload to one of the many hostings websites such as dropbox
or mediafire.com/

Thanks in advance,
Carnë
