Thank you for posting a picture in our community. However, it is important that you include the date in the picture so that people can see that the picture is up to date. There is a special app for Android and IOS for this. Here you can find the exact description of the rules. https://steemit.com/hive-135106/@greece-lover/regelaenderung-or-rule-change-or-cambio-de-reglas-or-izmenenie-pravil

If you also want to take part in the "Picture of the day" competition, then put the picture under the post that is updated every day and that can be found at the top of the wall. Thank you
