Much like shareasecret and keepsafe offers, there should be a feature for images or even videos being sent should time out after a period of time. Sharing of images are highly popular but they often hold very sensitive information. The user could select the time limit of the link to give them the choice of how long the receiver may keep the information or even include an option for a password to be needed at the once the page has loaded. Safety and security are much important features to be included through messaging. Thanks for reading!
