It won't work that way ; cp_r copies the whole directories.  You need to
use Dir.glob or Find.find to select the files and then copy them one by
one.

Again, pretty much untested :

  Dir.chdir("/public/uploaded/users/#{u.login[0..0]}/#{u.login}/logo") do
    Dir.glob("**/*.{jpg,png,gif}").each do |f|
      f2 = "/public/uploaded/logos/#{u.id}/#{f}"
      mkdir_p File.dirname(f2)
      cp_r f, f2
    end
  end

(You'll need at least to specify absolute paths if public isn't in the
root.)
