Large images on prototype help

Help NEW to Figma through coursera, My problem is when I play the prototype, the items I created in the canvas are veery large for the mobile device that I have choosen. How do I adjust this. I have adjusted the pixes but no help. Thanks

Hi there,

Thank you for using Figma! If you find that the image doesn’t fit the screen in prototype mode, could you try pressing the “Z” key to adjust the fit? You might find this article helpful:

If the problem persists, could you please share screenshots or the file link?
