If you know what the folders are called click on search then click "search hidden files and folders" and search the folder name. They will be found.

If you have changed the properties of the pics to hidden, then you need to :-

1. Open My Computer
2. Click Tools
3. Folder Options
4. View
5. This should bring up a list of options. Under Files and Folders, you will find an option for the setting of hidden files. If you want to see them again, you must select show hidden files and folders. But as soon as you do that, it is accessible again. So you will have to make sure you change it back again when you are finished.

Hope that helps.

I know, this is coming from computer illiterate here but how about doing a search. Right click on start and then search? Hope you find them. It is only 11pm here but should be going to bed myself here. Good luck

 Um, if its a mac then you could use Finder for recent activities.(i think,99o/o sure) Otherwise I'm stumped. Hope you find them! There must be a way!!
