Hi Justin,
Thanks for reaching out with your Crio Pro WordPress theme questions.
Your Crio theme uses the BoldGrid Post and Page Builder plugin to handle making edits to your post and pages. As long as you’re logged in to change images or text you just need to click the “Edit” page/post option at the top of any page.
Once you’re inside of the page editor click the image you want to change and click the “media icon” to change the image. But sure to update the page after making your changes.
We have a guide on working with images in the Post and Page Builder that you should help outline this process for you.
I hope this helps! Please let us know if there’s anything else that we can answer for you.
