Grab an image, throw it in your public folder, lets call it myimage.jpg. Run script/server to start your server, and in a controller somewhere put this:

require 'RMagick'

def show

image  = Magick::ImageList.new(“public/images/myimage.jpg”)
image   = image.rotate(90)
image.write(“public/images/myimage.jpg”)

end

then in your show.html.erb you can show your picture:

<br /> <img src = "/images/<strong>myimage</strong>.jpg" />

Every time you load the page you should see your image rotated by 90 degrees. This tutorial actually took me longer to write out then to complete, even so I hope this maybe helps someone else getting started out with this powerful program.
