Lists the images that can appear on gutter for gutter objects and bookmarks.
property Images: TCustomImageList;
Images specifies image list that are used by the gutter objects (including bookmarks). TCustomGutterObject.ImageIndex specifies index of the image associated with the particular gutter object or bookmark.
Alternative way is to use TCustomGutterObject.ImageList property of the paticular gutter object or bookmark. Using this property allows to use image in different dimensions.
