The default is null to use the standard images. If set, the image list should contain images in the following order:

Image Index	Description
0	Unthemed collapse image (required)
1	Unthemed expand image (required)
2	Themed collapse image (optional)
3	Themed expand image (optional)

If you do not need separate themed and unthemed versions, you may omit the last two entries.
