You have several options. Here's how to do it using RMagick¹:
require 'RMagick'
images = Magick::Image.read(filename)
images[0].display
RMagick depends on ImageMagick² or GraphicsMagick³ being installed on your system.

Install gtk2 in system,
Install gem Ruiby,
Then try this :
require 'Ruiby'
Ruiby.app do
stack do
ARGV.each { |fn|
label File.exist?(fn) ?
"#"+fn :
"Oups !! unknown file '#{fn}'"
}
end
end
(label show a image file if args start with #, else args text)

There is a jruby-specific library which can do this simply:
jruby -rubygems samples/file_view.rb ~/Pictures/hand_sanitizer.jpg
file_view.rb:
require 'image_voodoo'
ImageVoodoo.with_image(ARGV[0]) { |img| img.preview }
Some other samples:
image_voodoo also comes with a command-line util:
jruby -S image_voodoo --preview --flip_vertically --preview
~/Pictures/hand_sanitizer.jpg
image_voodoo --help for other options
-Tom
jruby -S image_voodoo --preview --

hi there -
how about Shoes? http://shoesrb.com/
green Shoes (https://github.com/ashbb/green_shoes\) is wicked easy to
install and use:
gem install green_shoes
once it's installed, you can just do this:
require 'green_shoes'
Shoes.app do
image 'TradyBlix.png' #(change the filename!)
end

The last line of my previous reply contains a pretty big hint.
If you get stuck, there's also this:

For Ruby versions after 1.9.0, I think you need to install rmagick2
instead of rmagick. Someone correct me if I'm mistaken.

Note, there is no such gem as "rmagick2". There is just "rmagick",
which happens to have had two major versions, 1.x and 2.x.
