Please correct this sentence I made when I had chat. When I had a chat with my friend and talked about the trip we had together before, I said "We couldn't have never too much pics together." ...I mean, I wanted to say the time we had is too short, and even if we took so many pictures, it would never enough for us to remember how we enjoyed. We should took a pics more. I know the sentence was wrong but I can't figure out what's the most proper words. Thank you for advance!
