Hi Parker,
You can upload images from the post or page editor by clicking the Add Media button and then clicking the Upload Files tab from the Media Library. This will attach the image to the post or page. If you simply want to upload an image, go to Media/Library and finally click the Add New button at the top.
If you need an easy, free video course on the fundamentals of using WordPress for things like adding posts, pages, images, etc., here’s a great link:

I hope this helps 🙂
