Image thumbnails

Hi,

I am trying to create image thumbnails and found this script:
http://www.cleverleap.com/ruby-thumbnail-generator/. Looks like image
is being scaled down and copied to cache folder, however nothing is
being displayed. I particularly don’t understand this piece of code:

cgi = CGI.new
cgi.out(“type”=>“image/jpeg”) { @pic }
render :nothing => true

I guess it supposed to render @pic which holds the image file, but
what does render:nothing => true mean?

thanks!

It means don’t include the application layout, just send the image.
