Images not appearing on Facebook & Google from Publicize

Several days ago images from our posts to https://www.sunnyjetsun.com are NOT appearing when the posts are shared to Facebook and Google+ using Jetpack’s Publicize. We have been doing simple daily posts for about a year that include a single image and a poem and they have always shown up on Facebook and Google+ with the image and the first few lines of the poem. Since about January 25th there’s NO image.

Here are the links all together:

Have searched, but haven’t found anything that shows why this would have changed. Thanks for any assistance.
