Image

Form tools provide a variety of powerful image manipulation options.

Attribute	Description	Default Value
ftStyle	Inline style attributes.	(blank)
ftDestination	Location of image; relative to the web root.	/images
ftImageWidth	Width to resize image to.	(blank)
ftImageHeight	Height to resize image to.	(blank)
ftThumbnail	Boolean toggle to pad out the image to the required width/height.	false
ftThumbnailBGColor	Is this replaced by ftPadColor?? Background colour for thumbnail padding. Colour name or web hexadecimal colour code.	white
ftPadColor	Background colour for thumbnail padding. Colour name or web hexadecimal colour code with double ## prefix.	white
ftThumbnailBevel	Apply bevel edge to the thumbnail.	false
ftAutoGenerateType	Options for autogenerating the image.	FitInside or Pad
ftCreateFromSourceOption	Generate image from source image. Requires a populated property called "SourceImage".	false

Not sure how the source image is determined. I think it's got to be a property called "sourceimage".
