Resizing images - i.e. making them smaller

Hi everyone,
I know that I can crop images or adjust them as a sqaure - but does Rise not allow me to resize images that I have imported (from my laptop or from the content libarary) via the editor? I'm trying to make an image smaller (full picture / not cut out) and this seems undoable - unless I resize the image first via Adobe on my laptop. Thanks for any advice.
