In Django you should use ImageField and define function that will generate "upload_to" parameter for your image :

def images_upload_to(instance, filename):
    return '/'.join(['images', instance.album.title])

class Image(models.Model):
    title = models.CharField(max_length = 60, blank = True, null = True)
    tags = models.ManyToManyField(Tag, blank = True)
    albums = models.ForeignKey(Album, blank = True)
    img = models.ImageField(upload_to=images_upload_to,null=True,blank=True)

demensions of image you can access in template by {{ image.img.height }} and {{ image.img.width }}

In this solution you cant use ManyToManyField to albums, becouse your directory structure is opposing it. If you wish to use ManyToManyField your images_upload_to function can't/shouldn't generate directory path based on one album. And in the first place, gallery images shouldn't be stored in static directory, but in media. Static files are are meant for js/css/images etc, that by definition are 'static' and won't change, but media files are for user-uploaded content.
