Downloading multiple images using PHP while - php

Question

The query returns 71 rows but only one image is downloaded. All image files are jpegs with 2 MB maximum file size; most are less than 1 MB. The fsize lines are commented out because they fail to return on the jpg image file.
I have no trouble opening the one image downloaded so I'm doing something right. How can I get the other 70 images? I'm not deep in PHP but I get done what I need to get done. Here's my code:
<?php
$query = "SELECT imagefilename FROM imageinfo WHERE accepted = 1 ";
$result = mysqli_query($connect, $query);
while ($row = mysqli_fetch_array($result))
{
$imagefilename = $row[0];
$sourcefile = 'http://domain.com/images/'.$imagefilename;
if ($fd = fopen ($fullPath, "r"))
{
//$fsize = filesize($sourcefile);
// if IE, otherwise Content-Disposition ignored
if(ini_get('zlib.output_compression'))
ini_set('zlib.output_compression', 'Off');
header("Content-type: image/jpg");
header("Content-Disposition: attachment; filename=$imagefilename");
//header("Content-length: $fsize");
header("Cache-control: private");
while(!feof($fd))
{
$buffer = fread($fd, 2097152);
echo $buffer;
}
}
fclose ($fd);
} //end while
?>

Patching together several postings, here is the working code I ended with.
//This puts the selected images in a zip file.
ignore_user_abort(true);
set_time_limit(0); // disable the time limit for this script
$query = "SELECT imagefilename FROM imagetable WHERE accepted = 1 ";
$result = mysqli_query($connect, $query);
if (mysqli_num_rows($result) == 0)
{
//Send message.
}
// common vars
$file_path = 'path_to_image_file';
$zipname = 'images.zip';
$zip = new ZipArchive;
$zip->open($zipname, ZipARCHIVE::CREATE );
while ($row = mysqli_fetch_array($result))
{
$filename = $row[0];
$zip->addFile($file_path.$filename,$filename);
}
$zip->close();
if (!file_exists($zipname))
{
//Send message
}
//This downloads the zip file.
//zip headers
if (headers_sent())
{
echo 'HTTP header already sent';
}
else
{
if (!is_readable($zipname))
{
header($_SERVER['SERVER_PROTOCOL'].' 403 Forbidden');
echo 'File not readable';
}
else
{
header($_SERVER['SERVER_PROTOCOL'].' 200 OK');
header("Content-Type: application/zip");
header("Content-Transfer-Encoding: Binary");
header("Content-Length: ".filesize($zipname));
header("Content-Disposition: attachment; filename=\"".basename($zipname)."\"");
header("Pragma: no-cache");
header("Expires: 0");
readfile($zipname);
exit;
}
}
?>
