Accessing image from image post

Hey there, I’m currently fetching all of my posts from a campaign and have the fields embed_url, and embed_data. I want to acquire the image that is attached to the post but my embed_data, and embed_url are both turning up as null. Are these not for the images? Thanks

The api currently does not support attachments. If the image is embedded inside the post content, it would come in. But if its an attachment or the main featured image in older image posts, it wouldnt come in.
