Running Cron Jobs to schedule tasks to run on your site is a good way of reducing the load on your WordPress site.
You can use a cron job to run the posting of images from all accounts or a specific account. The URL for all accounts is supplied in the settings and a per account URL to trigger that account is found in the ‘Useful Links’ box in the edit account screen.
The cron job command would normally be curl or wget then the url provided. For example:
curl -k http://mysite.com/wp-admin/admin-ajax.php?action=instagrate
