tkImgAdd(file, type = "gif", update = FALSE)
tkImgDel(image)
tkImgRead(dir, type = "gif")

`file`	image file from where to download the resource.
`type`	type of image. Currently, only 'gif' is supported.
`update`	do we update an already loaded image resource, or not?
`image`	name of an image.
`dir`	the directory that contains one or more image files to read.

These functions should not be called directly, but by means of imgAdd(), imgDel() or imgRead().

tkImgAdd() returns the handle to the newly created image invisibly. tkImgDel() returns invisibly TRUE if the resource is found and deleted, FALSE otherwise. tkImgRead() returns invisibly the list of image files that are imported as resources.
