deleted select photos previously synced to my phone but not the whole folder How can I delete select photos from my iphone 8 that were previously synced from my computer but I can't find the folder on my computer, a microsoft tech guy helped me get photos from the Microsoft photos opp onto my phone after I dropped my iphone 7 and couldn't get the pics off of it.
I would turn on iCloud sync of photos so you can use a computer to ohotos to be deleted or just delete them from a larger screen. 

For me, using a computer via photos is even better, but you might not have a Mac but just about everyone can borrow a computer to organize things easier than tapping on an iPhone.
