How can you implement a gallery?

Question

Django

There is a gallery model

class Album(models.Model):
    title = models.CharField(max_length=255)
    caption = models.CharField(max_length=1000)


class Image(models.Model):
    image = models.ImageField(upload_to='albums/')
    title = models.CharField(max_length=255)
    caption = models.CharField(max_length=1000)
    album = models.ForeignKey(Album)

and a template with select, albums are loaded into the select, when the select is changed, the contents of the div below change, specifically the images of the corresponding album
Where to dig or how can this be done?
