How to make tables in "Tides processing script - displaying graphically"

easiest way to center is to put this in to center tags like this

<center><img src="tides/low_105.jpg"></center>

if you use frontpage you can see the preview whilst you play with the code, you can clic on the image and choose center
and so on, good program for play and fixing html

Thanks.
I have asked the forum member who first put the script on the forum, to have a look at the errors that shows.
