Prevent Animated GIFs from Looping

We all know animated GIFs put the "fun" in "functional." I've recently written incredible posts with regard to animated GIF images, including:

• Detect if a GIF is Animated
• Merge GIFs with gifsicle
• Optimize GIF Images
• Convert Video to GIF or GIF to Video
• Get the First Frame of an Animated GIF with ImageMagick

One bit of information that has eluded me is how to control the loop count of an animated GIF.  Say you have an animated GIF and you only want to limit the number of times the GIF can loop, or even prevent looping of the GIF -- it's super simple with gifsicle!

Prevent GIF Looping

gifsicle provides a --no-loopcount option when you process a GIF:

gifsicle herrera-wtf.gif --no-loopcount > herrera-wtf-once.gif

The resulting GIF plays once and then stops:

Click the image above to restart it.

Loop a GIF {x} Times

Another gifsicle command line option, --loopcount, allows for you to set any number as the loop count of the image:

gifsicle jack-slow.gif --loopcount=3 > herrera-wtf-four-plays.gif

The --loopcount is set to 3, meaning the GIF actually plays 4 times (original, then 3 loops).

Why you'd want a GIF to loop at any specific amount is unknown to me, but the ability to prevent looping is certainly useful, if only to cut down on how expensive the animation is!
