I also like to visit a Google search page, click on 'image' link, search using desired keyword, and select appropriate images to place on my posts.

To delete the image, what I do is just click on the image and press the 'delete' key to the right of my keyboard.

If you follow the training as it’s structured you should be creating your posts and publishing them and going back at a later date to add images. I had created four posts before I got to the part in the training where I had to add images. It is at this same point that you then go into all of your past posts and add images to all of your past work. Kyle has structured all of this so that we do things at the appropriate times. The beauty of doing it this way is that there’s a video with a step by step walkthrough of exactly how to do it.

Hi heather if your creating your post in the site content section if you look across the toolbar that contains the headers H1 H2 H3 headers. Go to the second box ( I think ) on the right hand side which is the images button and click on it it will bring up the images page . You then just type relevant subjects in to the search bar and scroll through the images and select one it will then say save and insert. You select where you want it by placing your cursor at the end of a sentence or between two paragraphs.
Once it’s uploaded on the screen there are a few adjustments you can make to it in terms of aligning left right or central.
Hope this helps
