Editing Your Profile
Individual users can edit their profiles by clicking the Edit profile link accessed from the Profile page in the user menu (top right).
Adding a new picture
The "Choose a file" button allows you to choose a new picture for your profile. The picture must be in JPG or PNG format (ie the names will usually end in .jpg or .png).
To upload an image, click the "Upload a file" button from the list in the File_picker, and select the image from your hard disk.
NOTE: Make sure that the file is not larger than the maximum size listed, or it will not be uploaded.
Then click "Update Profile" at the bottom - the image file will be cropped to a square and resized down to 100x100 pixels.
When you are taken back to your profile page, the image might not appear to have changed. If this is so, just use the "Reload" button in your browser.
