You don’t need to insert the HTML for the form manually, just use {{form}} in the template.

{% block body_block %}
    <form id="upload_form" method="post" action="/rmb/upload/"
            enctype="multipart/form-data">

            {% csrf_token %}
            {{ form }}
    </form>
{% endblock %}

By default a ForeignKey will be a select field so you shouldn’t need to do much else.

As an aside, give your models and fields more appropriate names. We know these are all image fields, because they are on the image and make sure, unless your model is a collection of things, you give it a singular name. Lastly, when using a Foreign Key and item gets an extra field of fieldname_id that is just the ID, whereas fieldname is the property that gives the related item as well.

So instead of:

class Images(models.Model):
    image = models.ImageField(upload_to='images', blank=False)
    img_name = models.CharField(max_length=120, blank=True)
    img_date = models.DateTimeField(default=now())
    img_user = models.ForeignKey(User)
    img_cat_id = models.ForeignKey(Categories)

Use:

class Image(models.Model):
    image = models.ImageField(upload_to='images', blank=False)
    name = models.CharField(max_length=120, blank=True)
    date = models.DateTimeField(default=now())
    user = models.ForeignKey(User)
    category = models.ForeignKey(Categories)
