How do I upload an avatar for my group and what are the limitations?
To upload an avatar for a group you will need to be an admin in the group. While hovering over the group avatar on the main page of the group you will notice an outline with a pencil icon will appear, this means you have the ability to edit it. If you are an admin once you click it a modal will appear that will let you upload a new avatar. If you do not see this outline, clicking the icon will only refresh the page.
Please be aware that the new avatar must be 100 pixels by 50 pixels and no larger than 30kb. If your file does not meet these requirements it will be rejected.
