Sometimes people send pictures or videos of themselves to others online, perhaps to a friend’s mobile, on a video call, or by posting it on social media platforms like Tiktok or Instagram. This can feel exciting and fun at the time but all images can be saved or ‘screengrabbed’ by the person receiving it – even if you think you are using a temporary message app like Snapchat, where messages 'disappear' after 24 hours.

Once a photo is shared online, you have lost all control of it and it will be virtually impossible for you to undo. Even if you change your mind and delete the photo you uploaded or sent, other people may have already shared or screenshot the image and there is nothing you can do to retrieve it.

But the good news is that help is available. If something does go wrong online, don’t suffer in silence. It’s not your fault.
