Laravel: is function __construct required if passing a parameter?

I have a bunch of functions related to image processing so I made an ImageProcessing.php class for my controller to reference. I put the code below -- in my ImageProcessing class, do I need a construct function and if so, what would I need to put in since I am passing in the data I need already? I am new to Laravel from doing Kotlin for years so I'm still learning the ins and outs.

Controller

public function processSmallImages(Request $request)
{
    $imageId = $request->input('image_id');
    $image = Image::where('id', '=', $imageId)->first();

    return (new ImageProcessing)->processSmall($image->id);
}

ImageProcessing.php

use App\Models\Image;

class Image 

    public function processSmall($imageId)
    {
        $image = Image::find($imageId);
         //// do Image stuff

    }
