Finally, I dit it (pure javascript+HTML, nothing else):
http://gooo.free.fr/animCJK/official/samples/imageFactory.html
Note 1: the svgs folder of the demo online contains only the MakeMeAHanzi svg for the characters 鼠貓牛虎兔龍蛇馬羊猴雞狗
Note 2: the same code can generate images for any characters of animCJK project or MakeMeAHanzi project. Just put the svg files you need in the svgs folder (see below)
To make a demo on your own website that use all the svgs of MakeMeAHanzi project:
create a folder named "imageFactory" (any other name is ok)
create a subfolder of your "imageFactory" folder called "samples"
create a subfolder of your "samples" folder called "_js"
get "Animated_GIF.js" and "magicAcjk.js" from animCJK project
(https://github.com/parsimonhi/animCJK/tree/master/samples/_js),
put them in your "_js" folder.
Note that "Animated_GIF.js" can also be downloaded from Animated_GIF project
(https://github.com/sole/Animated_GIF/dist).
Note that Animated_GIF project itself is derived from several other projects.
Update 2018/11/05: get also "brushingAcjk.js" from animCJK project.
get the "svgs" folder from MakeMeAHanzi project
(https://github.com/skishore/makemeahanzi),
put it in your "imageFactory" folder,
or if you already put the "svgs" folder elsewhere on your website,
replace "../svgs/" in "imageFactory.html" file by a relative path to your "svgs" folder.
