Welcome to Steemit @amandasrz! I hope you post many pictures of your country. All the pictures I've seen have been very beautiful!
In case you haven't already seen Steemit is just one platform of the overall Steem community. If you haven't already seen you can replace many social networks by using Steem based platforms like this:
Replace Reddit for Steemit - www.steemit.com
Replace YouTube for D.tube - d.tube
Replace Twitter for Zappl - www.zappl.com
Replace Instagram for Steepshot - www.steepshot.io
Replace SoundCloud for DSound - www.dsound.audio
Replace Periscope for DLive - www.dlive.io
While each of these sites have a community built around their product offering for the Steem ecosystem, they all still post to the same Steem blockchain. So when you view on Steemit you will see all posts that go to the blockchain while viewing on the independent channels may restrict to just content that was created on their network.
Regardless of what platform you use to interact you still earn rewards based in Steem for participating. It just makes so much more sense than using the centralized platforms of the past! Anyways if there's anything I can do to help please just ask!
Thank you very much for your help and welcome, I will certainly ask you
