I plan to use a frames page to post my photography online.

In the left frame will be thumnails. Clicking a thumbnail will display the image in the main frame.

All my photos have a unique ID already - that's how I name them. So my database table looks like this.

ImageID
Filename
Year
Subject

Sample data

ImageID = 18482
Filename =18482.jpg
Year = 1995
Subject = Scenic

In the PHP page I plan to have two variables that get pre-pended to the filename

$ThumbPath ='\images\thumbs\'
$ImagePath = '\images\'

What is the code for

1) Populating the images in the left frame based on subject. I know how to write the SQL statement, but how do I make it actually display the thumbs?

The thumb not only needs to be displayed, but it also needs to be a hyperlink.

2) When the viewer clicks the thumb, what is the code for displaying the image?
