Solution:
This works for me , i tested locally, You don't need to for loop to do this
$dir = 'var/images/';
$extensions = array('jpg', 'jpeg', 'png', 'gif');
if( false !== is_dir($dir) ) {
$dir_contents = scandir( $dir );
foreach($dir_contents as $images) {
$file_ext = pathinfo($images, PATHINFO_EXTENSION);
if( ($images !== '.') &&
($images !== '..') &&
(in_array($file_ext,$extensions))
) {
echo "<img src='$dir$images' style='width:100px;height:100px;'><br>";
}
}
} else {
echo "Path is not directory";
}

Solution:
To be very specific to your problem, You could useGLOB to find out the files in the folder and then match them against your extension list and then display the images. you could use the following code to display all images with specific extension in a given folder.
$FILES = glob($PATH."/*.*");
for ($i=0; $i<count($FILES); $i++) {
$fileName = $FILES[$i];
$fileExtension = strtolower(pathinfo($fileName, PATHINFO_EXTENSION));
if (in_array($fileExtension, $ALLOWEDTYPES)) {
echo "<img style='margin: 10px auto' height='150' width='150' src='".$fileName ."' alt='".$fileName."' />";
} else {
continue;
}
}
generally speaking, you could also use a scandir as the other user mentioned in post above to achieve similar result to display all the images from a given folder.
$FILES = scandir($PATH);
foreach ($FILES as $index => $imageUrl) {
echo "<img style='margin: 10px auto' height='150' width='150' src='".$PATH."/".$imageUrl."' alt='".$imageUrl."' />";
}
