I think a restore from the recycle bin puts them back where they came from.
btw, to avoid problems like this in the future ALWAYS backup photographs to a CD or DVD so you know you can never accidently delete them.
Even if you dont back them up to CD or DVD at least make a COPY of the photographs and put then in "spare" folder on the hard disk, or even on a USB memory stick or external hard disk.
I ALWAYS back up my pictures as soon as they are copied from the camera to my PC, that way if I do delete them by mistake, or if the PC ever crashes, I know I have them safely backed up on CD or DVD.
