In Luminate: Add any of the tags below to your page or PageWrapper's <head> element to designate the information being passed to Facebook. These can also be set in the Page Attributes when editing your page. For more information
In Blackbaud NetCommunity: place an Unformatted Text part on the template (not the page) and set it to apply to the <head>, and add the following codes to the part exactly as shown.
Add the following codes: <meta property="og:image" content="url to image" />
- The thumbnail image or "icon" for your page. If you choose not to set an icon manually, Facebook will choose an image to use as the default thumbnail for you.
<meta property="og:title" content="title of the page" />
- The title for the post. If you choose not to add this property, Facebook will populate the page title with the title of your page.
<meta property="og:description" content="add a short description of the page or content"/>
- A short description of your page content. If you choose not to add this property, Facebook will select a section of your page for you automatically.
