ThumbsPreFetchSize

Use this parameter to configure the amount of thumbnail sets that are retrieved in the background. The actual number of thumbnails in a set depends on the zoom level.

The valid values for this parameter are the numbers zero (0) to seven (7).

A value of 0 means that no thumbnails are retrieved in the background, in addition to those already displayed on the screen.

The default is 2, which means that two sets of thumbnails are retrieved in the background, in addition to the set already displayed. These thumbnails are ready to be displayed as the user scrolls down in the thumbs panel, making the interaction seamless.
