Frankly, it's quite unclear to me what you want.  When I run your script 
  I see *all* directories printed plus image file names without a path. 
  If that is what you want, then you can do this in "one" line:

$ ruby -r find -e 'Find.find(".") {|f| if File.directory? f then puts f 
elsif /\.(jpg|png)$/i =~ f then puts File.basen
ame(f) end }'

Or, printed a bit more verbose and added handling of multiple base 
directories:

require 'find'

ARGV.each do |dir|
   Find.find dir do |f|
     if File.directory? f
       puts f
     elsif /\.(?:jpg|png)$/i =~ f
       puts File.basename(f)
     end
   end
end

Still very concise and readable.  The complicatedness of the original 
code cannot be attributed to Ruby.
