Tim has helped me in installing RMagick 1.7.0 but as I want to try the 
example, I encounter a few errors.

C:\images>irb -r 'RMagick'
irb(main):001:0> cat = Magick::ImageList.new("N-1.JPG")
=> [N-1.JPG JPEG 720x480 DirectClass 8-bit 65kb]
scene=0
irb(main):002:0> cat.display
Magick::ImageMagickError: X Window library is not available `N-1.JPG':
         from (irb):2:in `display'
         from (irb):2
irb(main):003:0>

Does it require X Windows server? Or, can it use Windows native display?

Thanks

Sarah

I just want to test that my RMagick 1.7.0 went fine.
