Multiple images in database with loop

I'm sorry to be a bother but I'm in this crap all day in a simple thing and I'm failing to see why. I'm trying to make a loop to insert in the database multiple data images. If you want to insert an image is working everything right but if I want to insert two or three it inserts only one. To insert two or three with the same table ID related I need to loop the problem I do a return $ C to count the number of images and it returns me always 1. Ando here back to back and this will always give the same. I have something wrong?

            $c = count($request->file('image'));
            $fileName = $request->file('image');

            for ( $i=0; $i< $c; ++$i) {
                $imagensportfolio = new ImagensPortfolio();         
                $file = array_get($imgportfolio,'image');
                $destinationPath = 'image/portfolio/';
                $extension =  $request->file('image')->getClientOriginalExtension();
                $fileName = rand(1111,9999) . '.' . $extension;
                $imagensportfolio->image= $fileName[$i];
                return $c;
                Image::make($file)->resize(700, 400)->save($destinationPath.$fileName);
                $portfolio->save();
                $imagensportfolio->Portfolio()->associate($portfolio);
                $imagensportfolio->save();   
            }
