When I'm browsing Safari for a new wallpaper..... I keep my finger on the picture until it asks me to 'save image,' 'open link.' 'or cancel.' When I save the image and then go into my photos..... sometimes the picture is blurry.... Heck, most of the time the picture is blurry. Is there a way to know before you save it if it's going to be blurry, or is it just a trial and error type of thing?
