Returns the new count of total thumbnails.

Remarks

This method does not wait for an image to be generated before returning. The thumbnail image is generated in the background. This means a thumbnail's image data (for example, its bitmap) is likely not available immediately after this method returns. Use the ThumbnailXpress.ItemComplete event to determine when an item's image has completed being generated before attempting to programmatically access its image data
