# Media Picker
The media-picker provides an easy way to use the [media manager](../media-manager) as a powerful formfield for your BREADs.
## Picking files
There are two ways to pick files.
1. Double click the file you want to pick
2. Select multiple files and hit the button "Select X files"
::: info
Files that are already picked will be removed when picking them again
:::
## Options
### Max
Defines the maximum amount of files that can be picked.
0 means infinity.
When using 1 as the maximum, the currently picked file will automatically be replaced when picking another.
### Meta properties
This option lets you add simple textboxes to every picked file.
For example, when you want to pick images, you could add a title and an alt-tag.
Click `+` to add a new property and add the key (for example `title`) and the textbox placeholder (`Title`).
::: info
Meta properties are translatable. Simply toggle the locale and enter the translated text!
:::
### Mime types
With this field you can decide which files can be uploaded and picked.
Simply add a new item and insert the mime-types you want to support.
Here are some examples:
- image/jpg - only allow JPG images
- image/* - allow all images
- directory - display directories
When no types are defined all are allowed.
::: warning
Note that a mime-type can not be guessed for all files.
Always consider official resources like the [official IANA MIME type list](http://www.iana.org/assignments/media-types/media-types.xhtml).

## Using media files in your model
Voyager provides a simple way to retreive files in your model.
To use it, include the trait:
```php
<?php
namespace App;
use Voyager\Admin\Traits\HasMedia;
class MyModel
{
use HasMedia;
// ...
}
```
You can now call `media(field)` where `field` is the column you use in the formfield.
`media()` will **always** return a [collection](https://laravel.com/docs/collections) containing your files.
The following properties exist on each item in the collection:
- Disk - The disk where the file is stored
- Path - The relative path to the disk
- Name - The name of the file
- URL - The fully qualified URL of this file
### Meta properties
Meta properties are automatically translated and injected into the items.
If you defined a meta prop `title` you can access it like `$model->media('field')->first()->title`
### Thumbnails
When a file has thumbnails you can iterate them like:
```php
foreach ($mymodel->thumbnails as $thumbnail) {
$thumbnail->url()
}
```
or get a thumbnail by its name like:
```php
$mymodel->thumbnails->where('thumbnail', 'crop')->first();
```
