Wallpapers (including Plus!/MCE):
All of these were taken from Getty Images except:
- Ascent. This was on Corbis and then taken down from Getty Images, but it is still available on a French stock photo site called Photononshop. Fortunately a full res copy from that site has surfaced.
- Bliss. Although Microsoft had bought the rights to it in 2000, meaning it could no longer be sold as a stock photo, Fujitsu at some point uploaded a full res .tiff of Bliss, which has made its way to many sites.
- Follow. This was taken down from Corbis at some point before 2014, though a high res version has been found. 
- Note that the colors of Azul, Tulips, Vortec space and Wind are slightly off. This seems to be due to them using Corbis RGB, which Getty doesn't seem to handle well. Stonehenge also appears to have been rescanned by Getty Images, so I also included an edited version closer to the original. 

The following are not present:
- Autumn. This was on Corbis and then taken down from Getty Images, but it is still available on a French stock photo site called Photononshop. While I asked Peter Burian himself if I could buy it from him, he has not responded. There is a version on DA that claims to be the original, but it's just an upscaled, dewatermarked version of one of Burian's later rescans. 
- Crystal, Home, Moon flower, Peace, Power, Ripple. Judging by the original file names as found deep down in the metadata, these may have not even been stock photos. Can't confirm or deny though.
- Purple flower. This was on Corbis, though the photographer's contract was not transferred over to Getty/VCG and therefore no high/full res version is available. 
- Windows XP. Created by Microsoft themselves, and they have not released a high res version. 
- Plus! Nature, Plus! Nature2, Plus! Space2, Plus! daVinci. Nature was taken down from Getty, the other 3's origins aren't even known. Most likely taken down from Getty before TinEye started indexing it.

Party Mode:
- Mostly taken from Getty Images.
- The 4 digit number in the filenames corresponds with the horizontal resolution.
- Nature's A wallpaper was taken directly from a PhotoDisc CD for higher quality.
- Nature's C wallpaper was taken down so it's not present.
- Frost's 1st and 4th wallpapers were taken down, although they have been taken from a Corbis CD.
- Frost's 3rd wallpaper was taken down too. A slightly different colored version of Frost's 4th wallpaper is on Alamy though I don't fancy buying it for now.

Sample Pictures:
- Sunset, Freestyle, Overlooking Rio and Surf were taken from Getty Images.
- Winter is no longer on Getty Images, though some guy called "moooon" uploaded several pictures they didn't even take to Depositphotos, including this and Aero Woods from Longhorn. Someone I knew bought both of those for me, which was long before I discovered stock photo CDs. 
- Blue hills is no longer on Getty Images either. It is on a Corbis CD called "Backgrounds from Nature", and while I previously had problems downloading its torrent, I eventually found a working one and got the image.
- Water lilies is also no longer on Getty Images. While I previously thought this one was gone forever, I finally found it in a torrent of a Corbis CD called "Four Seasons".
- At the Arch and Big Wave were taken from Corbis CD torrents.
- The remaining MCE and Beta sample pictures are unavailable in HQ.

Scanner & Camera Wizard: 
- Taken from Getty Images.
- The wizard only has one small graphic of marigolds, which is included here albeit in color. 

Starter Edition:
- All taken from Getty Images.
- A few of these are still available, but not included due to their vertical aspect ratios, so when downloading from ZeonDownloader they are not wide enough but too tall.
- Some are also not included due to them originally being panoramic, so they aren't tall enough at 2048px from ZeonDownloader.
- And as usual, some of these also got taken down from Getty. Some were on Corbis and never made it to Getty.
- Cerros_Torre_y_Fitz_Roy and Peter_the_Great also come with alternate versions. 
- The Uruguay, Thailand and Indonesia wallpapers haven't surfaced, so their filenames aren't known, so I went with their Getty names. I found them by reverse searching wallpapers edited from screenshots of people using these. On top of that, we don't even know what most of Thailand, Indonesia, Malaysia and Vietnam's wallpapers look like. Please consider buying XP Starter copies of these if you live in those countries.
- A few of the graphics from the tutorials are also included here in wallpaper form.

User Account Pictures:
- Mostly taken from Getty Images, except airplane which I found on a Corbis CD, astronaut I cropped it from a high res version found through reverse searching (it's a very common photo) and ball was bought from Can Stock Photo (although I don't think it originates from there)
- Quite a few of these are no longer available from Getty. Some of them, just like some of Starter Edition's wallpapers, are too tall and not wide enough to be cropped to 1920x1200.
- The Guitar one has a shadow and grey backdrop added in XP. The one here lacks this. 

Fun Packs: 
- Mostly taken from Getty Images.
- The 2003 wallpapers are the same pictures used in the XP MCE Party Mode Frost skin, but with different names.
- The card templates and Windows Movie Maker backgrounds have been lumped into the same folder for simplicity (yes I even included the 50's life card template background). 
- Unlike on the ones Microsoft used, no text is present on these. 
- Ones that are not present were either taken down or not large enough to be cropped due to them being vertical. 
- Half of the 2004 wallpapers are here; the other half aren't on Getty.
