No, the HD folder is the "on demand" one. If you own(ed) the card and click the image to view the full size one, the game will download it to that folder. All the MD images are downloaded to your device.

User:Kellindil Maendellyn has a program she uses to download all the HD images on demand, so I haven't bothered with it myself at this time.
