URL regex could look something like this:

url(r'^urlstart/(?P<image_id>\d*)/?$', 'urlstart', name='urlstart')

View code could look something like this:

def urlstart(request, image_id=0):
  if image_id == 0:
    image = None
  else:
    image = get_object_or_404(Image, image_id)
  next_image = image_id + 1

  return render_to_response('template.html', locals(), context_instance=RequestContext(request)

Template code:

{% if image %}
  <img src={{ image.url }}>
  <a href="/urlstart/{{ next_image }}">Next</a>
{% else %}
  Put your text here.  See first image by clicking <a href="/urlstart/1">here</a>
{% endif %}

Obviously this is simplified. For example, you may want to check to see if there is an image to come next.

Hope this helps.

Take a look at Pagination which will provide you with Next/Previous links, etc.

Also, it would probably be a good idea to use permalinks and pass the next/previous image in from the view instead of hard-coding the URL into the template.
