Google messenger not sending images.

Searched around and found that the app has some issues with apn's, and that it's a Google issue but could not find a an apn workaround.

It was fine and month ago, had sent some images to wife's note 4 that I had downloaded from Google images, still having the same images in the gallery I tried resending image, but now it fails to send,WiFi or regular data.

Any help will be appreciated.
