Image.read() is relative not to your web root, but to your host operating system''s root. Try something like: def index fname = RAILS_ROOT + ''/images/img2.jpg'' img = Magick::Image.read(fname) img = img.first ... end On 10/17/07, Mohamed Saeed <medofci-Re5JQEeQqe8AvxtiuMwx3w@public.gmane.org> wrote:> > def index > img = Magick::Image.read (''/images/img2.jpg'').first > width, height = 100, 100 > thumb = img.resize(width, height) > thumb.write(''/images/mythumbnail.jpg'') > end--~--~---------~--~----~------------~-------~--~----~ You received this message because you are subscribed to the Google Groups "Ruby on Rails: Talk" group.

I presume that the ''/images/ img2.jpg'' will be replaced with some variable that is meant to be an absolute "web" path, but you need a "file system" path. -Rob Rob Biedenharn http://agileconsultingllc.com Rob-xa9cJyRlE0mWcWVYNo9pwxS2lgjeYSpx@public.gmane.org --~--~---------~--~----~------------~-------~--~----~ You received this message because you are subscribed to the Google Groups "Ruby on Rails: Talk" group.
