How Can I Write A Widget Which Displays An Image?

Answer»

That’s easy. Just include an image TAG in the template of the widget:

class ImageWidget(widgets.Widget):

template = '<img xmlns:py="HTTP://purl.org/kid/ns#" SRC="${VALUE}" />'

and provide the image URL when you display the widget:

${myimagewidget(tg.url('myimage.png'))}

If you want to serve a dynamically generated image, you have to provide a controller method for this, and use the URL to this controller method as the value for the widget.
