What viewers can play GIF animated images?

On Manjaro running Fluxbox, I don't seem to have an image viewer that can play animated GIF files. I think that Gwenview can and I have it on my KDE system. But on a Fluxbox system I would like to avoid too many KDE dependencies.

Is there a way, perhaps with ffmpeg or convert, to constrain the size of a GIF created by stitching PNG files? This answer (Creating a GIF animation from PNG files) does not address this, and apparently the instructions are out of date.
