The ImageIndex property specifies the position of the image in the image list. The ImageKey property specifies the image itself.
The Image, ImageAlign, ImageIndex, ImageKey, and ImageScaling properties pertain to various aspects of image handling. Use images in ToolStrip controls by setting these properties directly or by setting the run-time–only ImageList property.
Image scaling is determined by the interaction of properties in both ToolStrip and ToolStripItem, as follows:
ImageScalingSize is the scale of the final image as determined by the combination of the image's ImageScaling setting and the container's AutoSize setting.
If AutoSize is true (the default) and ToolStripItemImageScaling is SizeToFit, no image scaling occurs, and the ToolStrip size is that of the largest item, or a prescribed minimum size.
If AutoSize is false and ToolStripItemImageScaling is None, neither image nor ToolStrip scaling occurs.
