If I like a picture on Instagram and then unlike it?

I liked this guys picture on instagram but then unliked it a few mins later. I know the person won't get a notification that I liked it if they weren't on instagram, but if they have their "notifications" set on for instagram on their iPhone, will it show up on their lock screen? As "___ liked your photo on instagram" even though i unliked it? Thaaaanku

There's no problem in that if you unlike that one.

  • Why does it hurt when you put sharpie on your skin & then take a picture with flash on the iPhone? Okay, so there's this thing at my school where you do this: 1. Draw a black sharpie square on your hand 2. Take off your phone case 3. Put your phone camera directly on the skin where your sharpie mark is 4. Turn on the flash on your phone and then take a picture. It hurts and stings a little bit. It's like a small shock. Why is that?
  • Picture editing experts: How do I edit a picture like this? I'm looking for a program or editing software (or iPhone app) to edit a picture like these two. And if you guys do know the program, do you also know what individual settings it takes to edit like this? Like sharpness, etc.
  • Make a video in iMovie and then record it with the Instagram or Vine apps? Will this work? If I make a little movie in iMovie, can I use the recording apps on Instagram or Vine to put it on their systems? There's some complicated editing I want to do and I couldn't do it on their apps to begin with. I was thinking of setting up my iPhone and just recording the finished movie with the Instagram or Vine app. I appreciate your help.
