Click Browse to find the image on your home computer. Then, click Upload. After you upload the image you will see it beneath the post editing window. Click on the image and and click the second option that appears above the image so that it says: “Linked to Image” then click “Send to editor”. The correct HTML to include you image will then show up in the post window. And the image will be contained in your post like so:
