As far as search engines are concerned...........enormous subject. The engines will find you, so don't get too involved in the meta tag subject. Condensing a volume into a few words - you'll improve your ranking if you make your site unique, or as near unique as you can manage. That might sound a little vague, but think like this:-
If your site dealt with the genetic implications and possibilities of breeding the rare lime-green Andalusian crested ferret you would almost certainly come right at the top of all search engine returns. Publish a site that showcases Kylie's best bits and you'll find yourself lost in a deluge of similar offerings.
In the world of the search engine being special is good. Make your site as interesting as possible, update it regularly, make sure your index page has text which adequately describes the content - "My Dad's picture site" is not going to be nearly as effective as "wonderful images of the Lake District".
Post that link to your dad's site and we'll get down to specifics.
