Snapchat Memories update will allow you to use old photos and videos

A new Snapchat update will allow users to save photos and videos and upload them at a later date.

Currently the app automatically deletes all files after 24 hours.

Via a blog the makers of the app said: "It's fun to celebrate an anniversary or birthday by finding a few old Snaps and stringing them together into a new Story.

"We'll be rolling out Memories selectively over the next month or so."

Snapchat, which launched in 2011, is one of the most popular social media apps in the world.

Last month figures were released that showed more than 150 million people use it every day.

In comparison, Twitter has 140 million active daily users.

However, Twitter is still ahead on active monthly users - it has 310 million compared to Snapchat's 200 million.

They both have some way to go to catch up with Facebook's 1.6 billion active monthly users though, while Instagram is on around 400 million users.

Snapchat has faced criticism though with some users accusing one of the app's filters of making people's skin "whiter".

The platform is known for its increasing number of funny and weird visuals as well as stories and live video calling.

Kim Kardashian-West and DJ Khaled are two of the most popular celebs on the app.

Snapchat has evolved rapidly from a simple exchange of quickly-deleted photos into one where users can tell the story of their everyday lives with photos and videos.

Snapchat was created at Stanford University by Evan Spiegel, with help from Bobby Murphy and Reggie Brown.

It was first known as Picaboo and was received poorly by classmates when Evan Spiegel presented the concept as his final project in his product design major.
