good day , is there anyway i can get photos and videos transferred from my iphone if i cracked my screeen ,

If the only damage is the screen you can take it to an Apple store (make a reservation) and they can replace the screen, usually without erasing the phone.

If you have previously synced to phone to your computer you can connect it and download the photos, but if you have not previously synced the phone this will not work.

It’s too late.

Backups must occur before catastrophes.

Depending on the phone damage you can always plug it into the computer and transfer data.

If you don’t see it as an icon on the iTunes Summary screen and you aren’t prompted to trust it then there might be additional damage.
