To add images to personal blog posts, do the following:

• When creating or editing a blog post, navigate to the Uploaded files section below the main text field and click Choose File.
• Select the image you’d like to add from your computer, click Open, and then press the Upload button. The image should now be listed just under the Uploaded files heading.

• Finally, click on the Add Macro button in the toolbar. Copy and paste the following line: (Image(your-file-name.jpg) failed - File not found)

• Replace "your-file-name" with the actual name of the image you uploaded.
• Click the Save button at the end of the page to publish your blog post.

Of note, you can also make some basic adjustments to the image's height, width, alignment, and more by adjusting settings in the Image editing pop-up window. Or, if you're using the editor's "Source" view, you can make changes by altering the HTML. If this latter option is of interest, a very helpful and concise guide to adding and modifying images using HTML can be found here: https://www.w3schools.com/html/html_images.asp.
