You may import your Instagram photos in your journal. To do this, you will need to connect your Instagram account to your journal
and select import period (once a day or once a week). First import will take place at 0:01 on the next day after you have enabled the setting.
Please note that if you wish your Instagram photos to be imported to LiveJournal, your Instagram account should be a public one. If you have cross-posting from LiveJournal to Facebook or Twitter enabled, your Instagram photos will not be duplicated there.
