Answer 1

Read about MongoDB data modelling here .

You could use just one collection for the functionality you have stated.

Sample document would be like :

{
    _id: ObjectId('fe67543457687798ab12'),
    url: 'www.example.com/img/qwerty.jpg',
    title: 'Image 1',
    description: 'Description 1',
    pagID: 'some ID'
}
