iPhone out of storage...

jo

My iPhone won’t let me take any more pics because it’s out of storage :( I have gone through & deleted tons of pics that I didn’t need, but it’s still full.. the remaining pics (ALOT) are all of my daughter, and I don’t want to lose them :( her birthday party is Saturday, so of course I’ll want to take more, but can’t. What kind of solution do you guys have? External storage? Should I try to buy a laptop to put them on? Any other ideas are welcome... Help!!
