I have found some pictures on the Internet that I would like to download to my Samsung Galaxy Tab S2 gallery. I touch the picture until a box shows up. The box has Visit - Share - Save. I click on Save and it goes into a screen that says Collection. I try to access it but I cannot find it. I have to go to the original picture I saved and in the lower right corner of the screen there is a box that says "View saved". I can view the pictures from here but I want to be able to use one of pictures as a wallpaper of my home screen. I am totally lost!!!!
A bit late to the comment but there is a second option.
When you find a picture that you want to use as a background but can not seem to save it, take a screenshot. Once you take a screenshot you will have the option to edit the picture (i.e crop the picture to your liking) then you can save the picture to your collection. From there set the picture as your background just like you normally would do.
