  title ||= "Watchr Test Results"
  message.gsub! /\[[0-9]+?m/, ''
  image ||= message.include?('0 failures, 0 errors') ? "#{IMAGE_DIR}/pass.png" : "#{IMAGE_DIR}/fail.png"

watch("spec/.*/*_spec.rb") do |match|

Growl works great, but the images aren't showing up even though they're in the "~/.watchr_images/" folder. Any ideas?
