Click your username or your current profile pic in the top left corner of the site to go to your profile. Click the yellow CHANGE PHOTO button, just below your current profile picture. (If using the site from a mobile phone or tablet, it will be a yellow camera icon without any text.)Either drag and drop your photo to the middle of the gray area, or use the green CHOOSE FILE button to select your photo. Uploading may take a few moments, and then you'll be given the option to crop and save your new profile picture! It can take some time to change on the site, so don't freak out if it doesn't change right away. If it still doesn't appear after an hour or so, try clearing your browser's cookies and cache. (Not sure how to clear your browser's cookies and cache? GOOGLE HAS MORE INFO!)Two important notes:1. Your profile pic is public, so while we love seeing your smiling face, you are welcome to instead use a photo of your dog or a nice flower if you're on the shy side. 2. Make sure your new profile photo does not violate SG's Terms of Service! Your profile photo can be anything you want as long as it is your own image and does not include copyrighted material, anything explicit, pornographic, hateful, or otherwise in violation of our TOS. In short, if it could get you or SG in legal trouble, it shouldn't be on the site, especially in your profile photo.
