You can set an import size factor during the importing operation in the tab next to the pen properties tab, at the top of the screen, above the drawing area. The content of that tab changes according to the ongoing operation.
Also you can scale the imported image afterwards like any other object with the scale command. After triggering this the image seems to be disappeared. This is a bug. Doing a "Auto Zoom" brings it back.
That png-image is not incorporated into the drawing file, you will have to provide it always alongside, best in the same folder.
