Has anyone used the thumb nail generator plugin

[bukaki]

I just installed this thumbnail generator http://www.cleverleap.com/ruby-thumbnail-generator/
and with it gd2 and the gd2 ruby binding library. Has anyone used
this. I am trying to create thumbnails from my images and i use the
following code in my view.

image_tag("thumb/photo.jpg",:h=>20,:w=>30)

nothing seems to happen but the name of the image is displayed. i
can't find any examples of this plugin being used. Any help is
appreciated.

working fine out for me....but I dont have much idea about

I'm using the File_column plugin. In File column plugin has its own thumbnail option. we can create whatever size of image we need.

Please go through the file column plugin to create a thumbnail of images.
