How to change or remove my cover photo in my Orkut profile

You can change or reposition your cover photo in your Orkut profile by changing it in your Google+ profile. If you have already linked your Orkut and Google+ profiles and want to change it, just follow these simple steps:
  1. Go to your Google+ profile.
  2. Click the cover photo.
  3. Select another photo and change its position.
  4. Click Save.
Your cover photo in Orkut will be updated automatically and may take some time before it takes effect.
You can opt to not show the cover photo in your Orkut profile. To do so, just follow these steps:
  1. Click the gear icon in the upper right, then select Settings.
  2. Click Google+ tab.
  3. Unselect the box "Show Google+ information in my Orkut profile".
  4. Click Save.
Note that your Orkut and Google+ profiles are still linked even if you hide your Google+ information.
Also, your profile name and photo are still visible and the same from your Google+ account.
