When using RMagick it's important to remember to destroy the image once you are done, otherwise you will fill up the /tmp dir when working with large sets of images. For example you must call destroy!

require 'RMagick'

Dir.foreach('/home/tiffs/') do |file|
    next if file == '.' or file == '..'
        image = Magick::Image.read(file).first
        image.format = "PNG"
        image.write("/home/png/#{File.basename(file, '.*')}.png")
        image.destroy!
end
