Answer 1

In your collection view controller add:

- (CGSize)collectionView:(UICollectionView *)collectionView 
                  layout:(UICollectionViewLayout*)collectionViewLayout 
  sizeForItemAtIndexPath:(NSIndexPath *)indexPath{

   //return the size of the cell based on image size or other criteria
}

Add constraints to the image:
