Photo captions are the words that are placed underneath a photograph, and these can be funny, memorable, serious, or even sad at times. Photo captions quotes show that these are common on social media sites that allow photo sharing, such as Facebook, Pinterest, Twitter, and others. You can find photo captions that brighten even the darkest days, and others that may bring you down. Often photo captions are used to describe the people in the photo, any activity that is being performed, or even the date, occasion, or event that is involved. People add photo captions to show others what is going on and who is in the picture, as well as to add something special that people will remember for a long time. No matter what photo captions you add to your pictures make sure that it is something that will help you remember when the photo was taken.
