How do you make your ícone move??

the ícones are GIF, that's how they r moving, u just have to find GIF picture

I'll tell you how, but you need a stick, a goat, some firecrackers, two magic necklaces, a bag and a plush toy dog!

Jk, just upload an animated picture from the Internet. They come in the GIF format, but apparently you need to convert it into a PNG, which is impossible since animated imagens can't be in the PNG format.
But since a few people have them, there must be a way. You should ask someone with an animated icon.

Poke it.

On Fanpop, I have no idea. I upload Gif format imagens on Tumblr and they work fine. But when I add them to my fanpop profile, they don't move.

fanpop has terrible servers.

Well, I typed in Gifs and clicked the first or segundo link. I don't remember. I wanted a Spongebob Gif so on the website I typed in Spongebob. I saved it to my computer. Also when you save don't forget to put .png at the end of it's name. If you don't, it won't move. That's how I got mine.

Use .png as the format.

Go to google and type in whatever it is you like, or go to gifsoup.com and find it.
Make sure the format is saved as png, not gif.
