My iphone 6 will not Save images when I click on photo or video so I can send it to ipad. the icon is completely gone and now it has Slideshow, etc. which wasn't there before today.
If you're using iCloud Photo, pictures you take or save from web sites will sync to iCould and if you're iPad is set to use iCloud Photo too - you'll see photos from your phone on your iPad automatically... not sure what else you could be meaning here...
