With Local Viking, you are able to schedule images to be uploaded to your GMB properties via the Local Viking dashboard.
From there, specify your category. After that select an image by using our gallery ( it's royalty free) or uploading your own.
Once you select the image, click on advanced and you now have the option to add EXIF data to the image.
After clicking the advanced tab, you can select 'recommended exif' button to automatically inject location specific data. We automatically inject the latitude & longitude coordinate of the location that the image is being posted to by default. You can add that independently as well.
Once you have completed the Exif data injection, you can then scheduled the post for a specific date and time. Keep in mind the post will schedule out according to the time zone that the location is in.
