Wer kann auf Instagram sehen, dass mir ein Foto gefällt bzw. dass jemand anderes mein Foto mit „Gefällt mir” markiert hat?
When you like a photo, it's visible to anyone who can see the post. Your followers may also see your username below a photo you've liked, no matter how many likes it has (example: 
[your username] and 12 others).
[your username] and 12 others).
After 4 likes, photos show the number of likes, along with usernames of some people you follow who have liked it.
If your account is set to private:
Only your approved followers can see your posts, including any likes and comments.
When you like a public post, your like will be visible to everyone and your username will be clickable below the post, but only approved followers can see your posts.
