IM HAPPY.gif

IM_HAPPY.gif is a fictitious animated image that was first mentioned in the creepypasta, The .GIF Is around creepypasta in 2011 by user Multiverseman.

The GIf depicts a yellow circle with a gray mouth and eyes, smiling towards the viewer(hence the name), the animation cuts into another frame of him being angry, and his eyes are slowly turning black, at which point the screen cuts into a slideshow of scary images including Regan MacNeil and Harlequin Fetus and others, before the text flashes "Have a nice day", but suddenly, the screen cuts into another picture of him, with no eyes, before ending the video with a black screen.

One thing to note is that aside from being a screamer, This GIF proves to be very dangerous and at the most deadly to anyone who views it, with it having very harmful effects on both viewers and their computers which is false there is no evidence of that happening.

Story
Another version of this GIF is older, released in 2007 on 4chans /b/ board. On March 12, 2007, on the /b/ board of 4chan, an anonymous user posted a .GIF image. At first glance, strangely, the .GIF image wasn't animated. It was titled IM_HAPPY.GIF, and showed what appeared to be a drawing of a smiley face, only with realistic-looking eyes and mouth. People who clicked on it saw the smiley face's smile slowly turn into a frown, and the eyes taking on an angrier appearance.

The smiley face would then scream loudly - loud enough to burst eardrums - and gruesome images of rapes, bomb test victims, aborted fetuses, mutilated bodies, and animals being tortured would flash by quickly. After about five minutes, it would show the text "Have nice day" (sic), and the user's computer would automatically close out of the browser and would stop working, as if a virus had corrupted the hard drive.

People whose computers were infected would shortly be found in their homes, skinned and mutilated, with a smiley face painted in blood on the floor next to their corpses. The founder of 4chan, moot, would always claim that the picture never existed, and that the murders were unrelated. However, somewhere in the archives, the picture still exists. Most people who attempt to post it are usually swiftly banned by the janitors of 4chan.

It scans the viewer with its eyes and mouth. Both serve as bits of code and objects for the scan, bypassing webcam permissions and automatically turning your webcam off if you view the gif longer than 5 seconds.

if the player didn't meet the criteria, the smiley face will start to grow into a frown. As it grows into a frown, behind the scenes, it is loading up the images and the audio file it will use. At this point, it might've opened a tab or two on your browser with pure coded gibberish. These websites are usually just blocks and templates for the code; there are also the names of the files hidden in the code. The files are typically named innocuous things with gibberish, like "ballboy9494838992382heunJ3.4.jpeg" or "sunshinevicitim949483022989928237465.txt.jpeg." The text part of the file is the file loading the graphics of the image. it normally disappears as the code grows and forms itself.
