I've added most of the avatars in this topic to Nintendo 64 Forever's avatar gallery. To get to the avatar gallery click on your username either at the top left of the page or beside any post you've made. Now you should be viewing your profile page. Click on "Profile Options" and then "Edit Avatar". There are several folders you can choose an image from but the N64-related images are in the N64 folder and there's more videogame related images in the videogames folder. Just click on the avatar image you want to use.
