I solved the problem many months ago, installing the plugin nodebb-plugin-imagemagick.

Use a gif image as avatar
I have a forum with NodeBB 1.2.1.
Some users want to use animated gif as avatar, but when they try to uplad the images only can select jpg, bmp or png.
I've installed the nodebb-plugin-imagemagick but nothing changes.
Is possible to use animated gif?
Thanks for your help.
