1 You are given 15GB of free online storage
with every Google account, but if you require more then click on the Google+ link in the left-hand column and then scroll down to the Photos section.
2 Here you will see how just much of your storage allocation
is being used. If you are close to your limit, click on the ‘Buy more storage’ link just beneath the ‘Upload my photos at full size’ option.
3 You will now be shown several upgrade price plans that offer a significant hike in online storage space for a monthly charge. Click on the option that best suits your needs and then you’ll be able to set it up.
