If your posts are set to public, you can add tags to your photos and videos that will make them visible on public tag pages.
- Take a photo/video and choose a filter
- On the screen you see after choosing a filter, type your #hashtag in the Caption field (example: #flower)
- If you want to tag a post you’ve already uploaded, just include your #hashtag in a comment on your photo
After you tag your post with a hashtag, you’ll be able to tap on the hashtag to see a page that shows all photos and videos people have uploaded with that hashtag. Read the blog post by Instagram for more tips on using hashtags!
