7.1, can't add photos to Blog Post

Site URL: https://easttowesthh.com/blog/zero-to-chickens-in-30-days

Any help would be greatly appreciated, I've created this blog post (the website built in 7.1, can't remember or find the theme) And cannot add photos to the blog post? There is only option for text? I added the thumbnail photo but want to add photos in the described aread in the text. Thank you in advance for your help and time 🙂

In 7.1 you go to edit post, hover around under the title and you will see an insert point, looks like a teardrop with a horizontal line, click on that then choose image  under basic or  a new layout under gallery. You will see add image, and the upload screen comes up.
