Here are directions on how to upload a preview image for sharing your site and define what content Facebook uses:

1. Upload an image that you would like to display with your links to your FTP account. You can do that via an FTP program or via File Manager in your hosting cPanel. The image should be square and at least 200 x 200 px. Also avoid spaces or special characters ($#+) in the file name.

If you do not have your cpanel/ftp login information and are hosted with us please submit a cPanel login request by clicking on the link below and someone will get it to you ASAP:http://bludomain.com/support

2. Go to your SEO section and under the custom meta tag field (usually for Google verification) enter the following meta tags:

<meta property="og:title" content="enter title here" />
<meta property="og:image" content="enter the url address to your image" />
<meta property="og:description" content="enter a short description" />
<meta property="og:url" content="http://YOURDOMAIN" />
<meta property="og:type" content="website" />

Be sure to replace the content portion with your own.
