So this girl on your friends list posted a nude and Saw it but didnt save it! Fear no more i shall teach you how to go re find that deleted photo using google chrome! To start type "about:cache" and you should find a hugh list of all photos/website inks etc... This might feel overwhelming but just use ctrl+f for the finder and type _n.jpg If using facebook. This looks for all the large files now its kinda of just a guessing game just highlight and click go to till you find that right photo. There you go now you have that photo that was once there!
