Adding an image to a page or post is not as simple as copying and pasting. See these instructions from Edublogs User Guide about Inserting Images, Pictures and Photos into a Post and Page.
**Also, consider how you will give credit to the creator of the image (even if it is you). This could be at the end of the post or page (like below) or in a caption (like above)
