First aid and sketchy images won't load

My Anking version 12 deck does not include any media from sketchy or first aid. It says " An image is missing" does anyone know how to fix this? New to Anki have watched YouTube videos but I am not getting it!

You need to import media separately, if you watch the Anking video on AnkiHub they demonstrate how to do this.

Hi, thank you so much. I did watch the video and sketchy worked for me but the First Aid still won’t show up. Any way I can fix this ? downloaded the sketchy media via the google docs link
