Validation: This is not the correct syntax. You are validating the fields 'image', 'mime' and 'max'. Please read the docu

http://laravel.com/docs/4.2/validation

As you can see, multiple rules for a field are separated by a pipe character '|' or as separate elements of an array. Your syntax should look something like this

$rules = array('image' => 'required|mimes:jpeg,jpg,png|max:200px');

or this (please notice the array inside the array)

$rules = array('image' => array('required', 'mimes:jpeg,jpg,png', 'max:200px'));

As for the db: This is a too wide topic to discuss here. You may check out this tut, which is for Laravel 5, but the creation of db table and the saving of an uploaded image/file is valid for L4 and L5.

http://www.codetutorial.io/laravel-5-file-upload-storage-download/

Essentially, you create a new instance of your image/file model

$image = new MyImageModel();

you add data, i.e. fill the columns of the db table

$image->column1 = $data1;
$image->column2 = $data2;
...

and finally you use Laravel's Eloquent to save the model

$image->save();
