OP clearly has no idea how regexes work. A pattern like /[http]{4}/ will match the strings hhhh and ptth in addition to the intended http. Furthermore he doesn't seem to understand that a dot (.) will match any character that could possibly show up in a URL, not just punctuation.

A sane version would look something like this:
def whichBoard(html_content, url)
  %w(a b c d e f g gif h hr co ic k).each do |boardname|
    host = 'http://images.4chan.org/'
    if url["#{boardname}"]
      regex = %r[#{host}#{boardname}/src/[0-9]{13}\.(jpe?g|png|gif)]
      return html_content.scan(regex)
    end
  end
end # end end end end end end

OP, please learn to use your tools.
