I believe this belongs in the forum/site help board ^^"
Anyways, there are two steps to putting a gif as your icon, but first you have to make sure it's small enough. I recommend something 100x100 or less just to be safe
Now, you can save it to your computer and simply upload it to your profile, or copy the link (or image location) and paste it into your profile. Make sure to go into profile >"forum profile information" > check the box depending on your choice above ("I will upload my own picture" for uploading from your computer or "I have my own pic" for copying the link from the internet) Good luck!
