If you’re like most people, you probably check Instagram every day to see if there are any new pictures or posts. But what if you don’t see anything new? What if someone has liked your picture and you don’t know who it is? There are a few ways to check if someone has liked your picture on Instagram. The first way is to look at the bio of the person who liked it. If they have a name and an account, they likely are the person who posted the picture. The second way is to look at their followers. If there are a lot of them, then they likely liked it. The last way is to look at their history on Instagram. If there have been recent pictures or posts with that person in them, then you can be sure that they liked your picture.
