Google Plus is a social networking platform from Google. It allows users to connect with friends, family, and colleagues, and share photos, videos, and updates. It also enables its users to join communities based on their interests and hobbies, and join Hangouts, which are virtual gatherings of up to 10 people. Hangouts can be accessed from any device, including computers, phones, and tablets. Additionally, Google Plus also offers features such as Events and Circles, which allow users to organize and share events with specific groups of people. Google Plus also offers integration with other Google products, such as Google Drive and Google Photos, allowing users to store and share their files and photos with others.
You cannot post and save images as G+, only short text bursts and small images.
