Gots tons of thumbnails clogging up your requests? Why merge them all into a single image / single request?

Library is whole dependent on Image Magick for processing files, the gem will let you know if it can’t find the necessary binaries

• After Save callback in Rails 3, using paperclip to regenerate an image based on changes

  after_save :generate_thumbnail_image
  def generate_thumbnail_image
     Allthumbs.generate (all.map {|x| x.image.path }), "#{RAILS_ROOT}/public/images/thumbnail-image.jpg", { :row => 3, :border => 2 }
  end
  

Comes with a complete rspec suite:

$ rake test

Develop some kind of helper to assist in generation of supporting HTML, e.g. you would like have rollovers or popups for each thumbnail

• Thoughtbot (heavily influenced by paperclip)
