Description:
GKrellM plugin that displays a periodically updating image
GKrellKam is basically wmGrabImage in a GKrellM panel, except that it is more flexible (you can specify a local or remote image, or a list of local or remote images, or a script that outputs the right image, etc). The image (any format or size) is resized to a thumbnail and placed in a GKrellM panel, where it is updated periodically. Multiple images are rotated. . This plugin is useful for keeping track of webcams, weather maps, or any other kind of changing image information.
