Now that we have brought back the use of avatars here at thechemicalforums, we've noticed that a lot of users have had extraordinarily large avatars. While we allow people to use avatars hosted elsewhere, we'd like people to kindly limit the size of their custom avatars to no bigger than 120x120 pixels. Anything larger than this really makes the threads move out of whack and can cause problems for people using lower resolutions. If an admin here notices that your avatar is too big, we will kindly remove the avatar from your profile and send you a PM asking you to reduce the photo size. Once you've adjusted the photosize, you can feel free to continue using the avatar. Thanks.
