Automate image display

The software I use to display images on a webpage requires that I complete the following entries for every image. I want a php script building which will enable me to place all the full-size images, the thumbnail images, the sizes of the thumbnail images, the alt tags / captions into the same directory and then? just tell the script where that directory is located. This is the html as it exists at the moment: <a id="hope-01t" href="images/[login to view URL]" class="highslide" onclick="return [login to view URL](this)"> ? <img src="images/[login to view URL]" alt="Fireworks? In Higginson Park" ? ? title="Click to enlarge" height="150" width="200" /></a> ? ? <div class="highslide-caption">Fireworks In Higginson Park</div> <a id="hope-02t" href="images/[login to view URL]" class="highslide" onclick="return [login to view URL](this)"> ? <img src="images/[login to view URL]" alt="Higginson Park Concert" ? ? title="Click to enlarge" height="150" width="240" /></a> ? ? <div class="highslide-caption">Higginson Park Concert</div> as you can see this demonstrates two images where the suffix "t" is the thumbnail. Captions and alt tags will always be the same. I will provide an installation of the program for the coder to test the script.
