Millions of people across the country have been switching their profile picture to an equal sign.
They're showing their support for same sex marriage.
The Human Rights Campaign put the image out Tuesday. So many people tried to download it, their website actually crashed.
It's a pink equal sign on a red background, a twist on their regular blue and yellow icon, the colors, representing the freedom to love.
There have also been a number of spin-offs from groups that oppose same sex marriage, many depicting an image of woman and a man with a red background.
