Controlled vocabulary exists for keywords in fields, but not for captions. There is no thesaurus. Descriptions are sentences that include objects and subjects. Sometimes actions, attitudes, and contexts are described. Results display as thumbnails, with title, date, and description, or you can see hits in briefer form.
Full record is accessible by clicking on thumbnail.

Because there is so much description assigned to each picture, searching is efficient, and you can be fairly specific about what you want. When you first enter the site, you'll see a screen listing the software required to use the system. If you don't have these programs, you can download them right from this screen. Having to have them is a bit of a pain, but once you go through the process, you'll be set up for not only Hulton Getty, but all sorts of other sites.
