How to find hidden pictures on my personal comp

if it's winows, Windows Explorer should have a search function that looks for picture files. I'm assuming the hidden pic still has a file extension related to pictures, i.e. gif, jpeg, png, etc.

even lookin for jpeg and all that no picsare showing up

Try using the *.jpg or *.jpeg in your search parameters. (or whatever file extension you may be looking for)

Maybe they were saved in another format, How do you know they are there if they are hidden? How did they get hidden? If they were downloaded and saved to a temp file they may not be there anymore.
