Doesn’t seem possible does it? Since there are hardly any images in Lexis-Nexis Academic documents. All true, but when an image is included in an article it is tagged with metadata that is maintained and can be searched on. As Jennifer Matheny explains in a Lexis-Nexis Wiki post a couple months back:
Are you curious to see how many newspapers re-ran an Annie Liebovitz photo on a particular day? Do you want to know how many Getty Images are used by newspapers this month? Use the GRAPHIC section in your search!
On the Power Search form, select a publication or a group file. Then, the Add Section search should pop up. Select “GRAPHIC” from the drop-down box. Type in your term and click the blue Add to Search button.
Of course you still can’t view the pictures but sometimes all you want are counts, pictures of Palin versus pictures of Biden, for instance, or such search results provide an interim step for locating pictures elsewhere–on microfilm or electronic files that offer page facsimiles.
