I have uploaded an image to view in the teaser just a simple 600 x 100 px image. It seems to not show in the node when uploaded. On my offline site it works fine.

Check your image-toolkit settings.

Perhaps the php graphics extension isn't installed or enabled?

You need php5-gd or php5-imagick, or both.

To check your php configuration you can run:

phpinfo.php

<?php phpinfo() ?>

Also how do you set the number of teasers you would like to display?

D6 or 7??

/admin/content/node-settings (posts per page) in Drupal 6.
