Adding an image to your event posts helps them stand out more on the calendar. Just be aware that many BlueBroward members will see your event as part of a weekly calendar roundup, and some email programs will not display the images. That means your image should provide additional value, but basic details like location and contact info should be included in the body of the post.
This video shows how you add an image to an event posting to the calendar or a post to the blog.
If you hoover your mouse over a new paragraph, you should see a + sign appear in the left hand margin that allows you to switch between adding text and adding an image. The same technique will allow you to add a YouTube video or another sort of content.
To insert an image between two paragraphs, hoover your mouse in the space between them and you will see the + sign appear between the two paragraphs. Or hover it over the first paragraph to get a + button that will allow you to add an image at the top of the post.
In the sidebar on the right, you will see options for whether to show the image full size or a smaller size, and whether to change how it is aligned relative to the text of your post (centered, aligned right, or whatever).
