1. How do I use a wallpaper?
Choose the size you want. The image will open in a new window. Right-click on the image in the new window. Choose "set as background" or "set as wallpaper", depending on what browser you use. That's it.
2. Why is a wallpaper not available in my size?
for your screen resolution.
3. Can I edit a wallpaper and/or use it as something else?
Not really. If you must, at least first.
4. I have a question. How do I contact you?
