Lost Photos

I needed to quickly download some photos to my ipad from a SD card. I was trying to download 93 pictures. My ipad kept telling me that I didn't have enough space, so I kept deleting photos and videos to allow enough space. I kept deleting and deleting, trying to free up enough space. In the end I had to delete over 900 photos and videos just to download the 93 I needed. I have a new iphone with lots of space, so I never thought the photos I was deleting from my ipad would also disappear from my phone!! I also had to delete the recently deleted pics to make enough space. Now I can't seem to find all of them! Are they really gone?? I never thought deleting them from my ipad would delete them from my phone! I can't even seem to find them in the cloud. Anyone have any advice?? Besides getting a new ipad with more storage, which I will do!
