Hi Confused,
well you've certainly circled all around it !
First, a basic error,
You've listed the files in a particular directory but neglected to tell the
HTML image tag what the directory name is !
Second, not really an error, but you can nest single quotes inside double
quotes to avoid all the confusing escaping.
Try This
<?php
//Open images directory
$dir = opendir("images");
//List files in images directory
while (($file = readdir($dir)) !== false) {
echo "<img SRC='images/".$file."'><br />";
echo "filename: " . $file . "<br />";
}
closedir($dir);
?>
note the SRC attribute is in single quotes with the double quotes
encapsulating the srings.
Cheers
Ron
