Linking to a WordPress blog post in Facebook with image thumbnail

When linking to a WordPress blog post from Facebook, often the incorrect image appears, or there is no image at all. Not long ago Facebook changed the way that link previews appear in an attempt to limit face news. As a result, images often don’t appear correctly. One fix is to add an Open Graph meta tag. One way to do that is using Meta Tag Manager, a free FB plugin. This tells Facebook to use the indicated image for the link thumbnail. Here’s an example from an earlier blog post:

<meta property=”og:image” content=”http://restondigital.com/wp-content/uploads/2019/01/Photo-Coordinates.png” />

The first test seemed to work fine. Time will tell.

Getting coordinates from Apple photo

Photos taken with an iPhone are tagged with coordinates. The coordinates can be displayed on a map in Photos, the lat/lon coordinates don’t appear to be accessible in app. To determine the lat/lon coordinates, export the photo, then open in Preview. Use Tools>Show Inspector and select the info tab (i). One of the options is GPS, which shows the latitude and longitude coordinates. It also lists photo Altitude, Destination Bearing and Date Stamp.
