According to the experts, there’s no such thing as a deleted photo. Because even if you’ve moved your images to ‘trash,’ chances are that they’re still out there. When taking such photos, use a drive with encryption software. It’s the only way to keep your photos safe and unseen because it’s unreadable unless you have the password.
The chances that these photos will surface again are rather remote and there is no point in losing sleep over this issue.
However in the case where these are brought to your notice by family members, or your social circle, respond quickly. Contact the authorities. Don’t panic. Often the authorities can help with the perpetrators of the crime but are unable to act if the photos / video has been uploaded to servers located outside their jurisdiction. Be prepared to deal with getting your pictures / video taken down as a separate issue.
It is wrong to assume that once your photo or video is taken off the issue is resolved. It could have been copied and uploaded somewhere else. The longer the content has been up the more likely it has spread to other networks and websites.
The best thing to do is to just relax and tackle the problem when it arises.
