` client/Windows Portable Elevation` is currently convert to `client/windows-portable-elevation` in hugo
But it shouldn't have capital letters and space, so changed to  `client/windows-portable-elevation/`

Change the image path to relative path instead of absolute path, because `images` folder will always on same folder of `.md`
