If you like nice backgrounds and screensavers on your computer you will love this site. Just go to https://webshots.com and sign up for free.
There are thousands of pictures there for download and they add new ones every day.
I love their scenery pictures and if you go to the part that says community center you will find ones that have been taken and submitted by members which I think are some of the nicest ones they have.
No matter what your taste you will find it here. You can use the search feature and type in a type of photo you like and it will show them to you. There are so many categories such as angels, lighthouses, cats, dogs, paintings, horses, water scenes, anything you can imagine.
You are always given the choice to download one picture at a time or the whole collection.You will get a little camera icon that flashes everyday when the new pictures are up.
If you bring up the album you will see everything you downloaded in categories if you want to change the wallpaper or it will rotate by itself.
The screen savers automatically will rotate showing every picture you have downloaded.
It is free and fast and I would recommend this to anyone.
