It is possible for your photos to get lost on Facebook, but it’s not very common. Facebook has a large amount of storage space, and it is designed to store and manage millions of photos and other types of media.
However, there are a few things that can cause photos to be lost or difficult to find on Facebook. For example, if you delete a photo from your profile or from a group or page that you manage, it will be removed from Facebook’s servers and will no longer be accessible. Additionally, if your account is suspended or deleted by Facebook for violating its terms of service, any photos associated with your account may be removed as well.
There is also a small possibility that a technical issue or glitch could cause your photos to be lost or temporarily inaccessible on Facebook. However, in most cases, these issues are quickly resolved by Facebook’s technical team.
To avoid losing your photos on Facebook, it’s a good idea to regularly back up your photos to an external hard drive or cloud storage service. This way, even if something does happen to your photos on Facebook, you’ll still have a copy of them stored somewhere else.
