What about just converting it to a 2-dimensional array in the view?
For example, using grouper() from the itertools recipes [1]:
def grouper(n, iterable, padvalue=None):
"grouper(3, 'abcdefg', 'x') --> ('a','b','c'), ('d','e','f'),
('g','x','x')"
return izip(*[chain(iterable, repeat(padvalue, n-1))]*n)
Images = grouper(4, Images)
Then, the logic in the template is straightforward:
<table>
{% for row in Images %}
<tr>
{% for image in row %}
<td>{% if image %} ... image detail ... {% endif %}</td>
{% endfor %}
</tr>
{% endfor %}
</table>
