System Restore will not restore pictures, documents or videos. It only restores files which are required for Windows to work properly.
If you saved all your pictures in the "My Pictures" folder, uninstalling Kodak EasyShare does NOT remove any of your pictures. If your pictures are missing, something else has caused it.
You may be able to recover them with file-recovery software if they've been deleted accidentally: http://pcsupport.about.com/od/filerecovery/tp/free-file-recovery-programs.htm
