Resize Rise Images

Hello,

I am wondering if there is a way to resize images in Rise? I am using a lot of the Labelled Graphics and Images in my course and I have received feedback that the images are huge which causes a lot of scrolling. I am currently taking screenshots of a cellphone screen for the photos, and they are ending up being very long.

I have tried to look up other discussions but haven't had much help on sizing. I am creating lots of graphics in Canva for Rise as well and would love to know the suggested size dimensions I should be using for different types.

Any help is super appreciated!
