How does image sitemaps works?

Hello there.
Have a read at this:
https://support.google.com/webmasters/answer/178636?hl=en

This thing shows me how to create an image sitemap. The thing is, they say I can include my image sitemap in my main sitemap (the one that contains links to posts, etc)

How could I do that? Should I simply link my image sitemap inside my sitemap?

Or should I include all the links and images in one? (But if thats possible, how can I format it so Google understands?)

Sorry if its hard to read!
Cheers.

Any clue? Ive been searching for the past hour to no avail.

This should work. Google will follow the links to your image sitemap. Make sure to format it properly.
