First create an image:
image create type ?name? ?option value ...?
Creates a new image and returns its name. type specifies the type of the image, which must be one of the types currently defined (e.g., bitmap). name specifies the name for the image; if it is omitted then Tk picks a name of the form imagex, where x is an integer. There may be any number of option-value pairs, which provide configuration options for the new image. The legal set of options is defined separately for each image type; see below for details on the options for built-in image types. If an image already exists by the given name then it is replaced with the new image and any instances of that image will redisplay with the new contents. It is important to note that the image command will silently overwrite any procedure that may currently be defined by the given name, so choose the name wisely. It is recommended to use a separate namespace for image names (e.g., ::img::logo, ::img::large).
Then you use the image you have created with the -image parameter. Bob Rashkin
