Answer 1

In Product model:
public function image()
{
return $this->hasOne(Image::class, 'pro_id');
}
In Image model:
public function product()
{
return $this->belongsTo(product::class, 'pro_id');
}
In controller:
$img = product::find($id)->image->filename;
Make sure there is a record for the product in the image table. Otherwise you have to manage the errors.
