Both functions create a new image that you can use instead of the old one, for example. You can then simply delete the old image if you like. To draw an image, either cal someWidget->image(myImage), which will make the image part of the label for that widget, or derive your own widget and override the draw() function to draw you custom widgets with your own ideas on where the images go.
