You can see the reason Yumeno gave for the versions on the pictures' pages.

http://ayakashi-ghost-guild.wikia.com/wiki/File:Planetarium_Amusement_Park_Wallpaper.jpg

like here if you scroll down and go to "File History", you'll find different versions of the pics and a comment about the reuploads. For all of the wallpapers, the reason is "Uploading full size version".

If there's anymore you want to know, ask YumenoUkihashi.
