My pictures folder, by default, is located in my documents folder. But in case if you want to move it to some other location you can do it by editing the “My Pictures” registry key under the following node.
HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Explorer\User Shell Folders
Instead of opening registry editor and editing the key manually you can simply run the following command in a command window.
The above command will make e:\pictures as the location for “My Pictures”
