A bookmarklet I whipped up to do something-or-another on Twitter. ;) I forget exactly what now; just didn't want to lose this code. =)

gistfile1.coffee

$('.tweet').each ->
    $tweet = $(this)

    # ignore tweets from ABC and DEF user IDs
    return if $tweet.data('user-id') in [123, 456]

    # also ignore tweets we've seen
    return if $tweet.data('image-opened')

    $openLink = $tweet.find '.open-tweet'
    $openLink.click()

    $photo = $tweet.find 'a.inline-media-image img'
    $permalink = $tweet.find 'a.permalink-link.js-permalink'

    return if not $photo.length
    window.open $permalink[0].href
    window.open $photo[0].src + ':large'

    $openLink.click()
    $tweet.data('image-opened', true)
