This snippet will create an image with text beneath it surrounded by a light gray box. The image can be left or right aligned so body content wraps around it if it is not the full content area width or center or left aligned with no wrapping. If you have cropped an 800 Banner or 1024 Feature size of the image being displayed, the system will automatically include a pop-up of the image and caption.
The Properties button in the Page Actions Toolbar near the top of the page contains information about the page. You must have the page checked out to you to see all the options.
MultiEdit Content is where you will set up the main page image if you are using a Feature Image. Select the MultiEdit Content option from the left menu in the Properties screen or by using the orange MultiEdit button at the top of the page edit screen. These options will be different for a Profile Page.
