You also have the themed photography contests :
For the tags I would say that it depends on the subject of your photos, whether they are landscapes, animals, cities, cars....
you can also post on communities related to your photo subject :
If you have birds photos you can post them in Feathered Friends community run by or post under the hashtag FeatheredFriends
if they are flowers you might want to post them in Always a Flower community run by
explore the communities here and find the ones that suits you 😉
Hope that helps
