Well, if you have the DVDs, like I do, there's always the option of turning the subtitles off. On the other hand, I've done a fair bit of screencapping on my own - I seem to be one of the only people who honestly likes the English dubbing better; the Japanese is a bit too emotionally subdued for my taste - so if there's an image you want, I probably have it. ;)
