If a document has an image associated with it, selecting this option will open the image automatically when you view the document. See Associating an image with a document for information.
Where images are displayed, keep them on top of other Perceptive Search windows so they are always visible.
When displaying images associated with a document, use your default external image viewer, not the built-in Perceptive Search image viewer.
If you use an external image viewer to open images associated with documents in the Perceptive Search result list, keep the Perceptive Search browse window open. If this option is not selected, the browse window will close when viewing a document.
Type in any file extensions you would like Perceptive Search to treat as image files and thus launch in an image viewer.
