Yahoo! made an update today to show Getty images inside of their image search for travel related queries. The query they showed was 'seattle washington' and indeed it brings back a lot of Getty results. The new Getty images take up the first 2 rows of search results, followed by the Bing powered image results.
This should be a great revenue stream for Getty who is not monetizing the images directly, but will most likely be on the lookout of people using them without paying for the royalties and taking/threatening legal action.
