Image thumbnails


I am trying to create image thumbnails and found this script: 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.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?


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