It has been a few years since I was regularly posting theme based wallpaper collections here at the site.
When I was actively sharing these themes through the WindowsObserver.com Downloads site, I would post three different downloads. Those downloads would consist of themepacks for Windows 7 and Windows 8. As you might recall, the format of the Windows Themepack file changed between Windows 7 and Windows 8 so it was necessary to post both. In addition, I would also post a folder containing the wallpapers included in those themepacks.
As I was recently cleaning up my downloads and themes collection, I decided to pull the specific themepacks and stick with the wallpaper collection download. This gives you greater flexibility on where you use those images whether you are on PC, Mac, or Linux.
So as you browse the downloads section of the site you will see this shift in the listings. I added several new collections over the last week and wanted to highlight them here. As new collections are added in the future, I will write them up so you will see what has been added right away.
Note: If you have any ideas for wallpaper collections just let me know.
You can check out all the other wallpaper collections, which include images from my own camera, NASA, Bing, and others. I will also be expanding these categories as I once again begin building the collection.
