Hiding a jak in a GIF is a matter of making a slideshow GIF with at least 2 frames: the original image, and the reveal. You can then set a time delay between frames so that, before you fags start implying, it's a gif, and if you load it and wait long enough it turns into the second frame revealing the jak.

Hiding in GIFs

You can hide a jak in a GIF image, but it's not as trivial as hiding in a static image though. Hence this guide.

Hiding a jak in a GIF is a matter of making a slideshow GIF with at least 2 frames: the original image, and the reveal. You can then set a time delay between frames so that, before you fags start implying, it's a gif, and if you load it and wait long enough it turns into the second frame revealing the jak.

On 4chan, the thumbnail of GIF posts is always the first frame. By setting no delay between the reveal, and disabling looping, you can make an image that looks normal in the thumbnail, but "magically" turns into a soyjak when expanded.

Tools:

GIMP

  • Each animation frame is a layer.
  • Specify the delay in the layer name. Write the delay in ms enclosed in brackets ()
  • Preview the animation: Filters → Animation → Animation Playback
  • Export with a .gif extension. A final dialog with settings, such as toggle looping, will show up.

ImageMagick

ImageMagick is a command-line image editor. Once comfortable with the tool you can pump out stealth jaks faster than with a graphical program. You can re-use commands by simply changing the input files (highlighted in bold). This command makes a "thumbnail reveal" for 4chan:

magick <filepath of bait image> <filepath of reveal image> -resize '%[fx:u.w]x%[fx:u.h]^' -gravity center -extent '%[fx:u.w]x%[fx:u.h]^' -loop 1 -delay 0 output.gif

Options you may want to change are italicized.

-loop
Set to 0 to loop forever, set to 1 to disable looping, that is, simply stop at the last frame.
-delay
Set the delay in centiseconds (100ths of a second). -delay 100 would delay 1 second; 2000 would delay 20 seconds, and so on. Set 0 for no delay, obviously.


Scriptfag made a set of 3000 "thumbnail reveal" gifs, using randomly-picked images from boorus. Coomer bait images taken from safebooru turn into soyjaks randomly picked from booru.soy. "Because the bulk amounted to 1 Gigabyte, I've split it into 3 sets for download"[3]:
