How do you set the image of the profile?
Also, do I'll do and how do the settings, such as video (?)?

Okay,

To set the image of your avatar, get an image and download it to your computer.

Hover the cursor above on your current profile image and click on “Change.”

Find your downloaded image, click on it.

Now you just have to wait for the image to appear- A great tip is to change languages to Edible Scratch then to English.

Video….

I assume you mean .gif files. Same goes above but just find a gif file.

I don't understand that part. I know what Edible Scratch is, but why would it help? Can you explain further?

Click here.
Then hover over your profile picture, to the left of your username.
Left-click.
Find the image that you would like to change your profile picture to.
Done!
You might want to find a square file or else it will be squished.
