namespace App\Http\Controllers;

use Illuminate\Http\Request;
use App\ImageGallery;
use DB;
use Intervention\Image\ImageManagerStatic as Image;

 public function upload(Request $request)
    {
    $this->validate($request, [
        'image' => 'required|mimes:jpeg,jpg|max:90480'
    ]);

    $input['image'] = time().'.'.$request->image->getClientOriginalExtension();
    $request->image->move(public_path('images'), $input['image']);


    if($request->hasFile('image')) {

$image       = $request->file('image');
$filename    = $image->getClientOriginalName();

$image_resize = Image::make($image->getRealPath());              
$image_resize->resize(300, 300);
$image_resize->save(public_path('images/ServiceImages/' .$filename));

}
$request->image->move(public_path('images'), $input['image']);

ImageGallery::create($input);

    return back()
        ->with('sucess','sucess');
}
