Rather than producing content, search companies should stay strong at search, whilst being decent to websites that merit this (ie, not scrapers, blatant MFAs and so forth).
This indeed means sending traffic where traffic's due.
In the case of images, a clear rip-off to show full-size versions. I'd hope there were some google engineers saying this wasn't right, even as bean-counters and the who-cares-about-evil folk pushed for them.
I'm not sure how valuable big images are in search engines; if truly better than thumbnails [why? - some people can't see small ones well?], just maybe could have some kind of big n obvious watermark thingy (copyright not ours: click to visit website and view proper version, say). Tho even this maybe not good.
