Read multiple image php - php

Question

I have two separate files, one is to display the html/php document image, and the other is a php file that renders the image using the header function content-type:image/jpeg.
I tried using it with one image and it works well. However, I need to display multiple images. How could I do this?
The html/php doc has an img tag that points out to the php file that renders the image
echo "<image src=Image.php>";
The image.php
$selectimage = mysql_query("SELECT Image from ImageTbl", $con);
if($selectimage)
{
header("Content-type:image/jpeg");
while($row = mysql_fetch_array($selectimage))
{
echo $row["Image"];
}
}

Answer 1

make two files one for image another for fetching the row like this
image.php
$image_id = $_GET["id"];
header("Content-type:image/jpeg");
//query database to get only one image from id
echo $row["Image"];
another file
getimages.php
//query for image data
while($row = mysql_fetch_array())
{
echo "<img src='image.php?id=$row[id]' />";
}

You can't output all the images together, because to the browser, it will look like the data of multiple images mushed together, which is nonsensical. Also, each image tag can only display one image. To solve this, give the image table an ID field to identify the image.
Then in the file that outputs HTML, do something like this (passing the ID for the image you need):
echo "<image src='Image.php?id=1>";
echo "<image src='Image.php?id=2>";
echo "<image src='Image.php?id=3>";
And then in the file that outputs the image, do:
$id = intval($_REQUEST['id']); // intval will validate the ID to be an int
$selectimage = mysql_query("SELECT Image from ImageTbl WHERE id=$id LIMIT 1", $con);
if ($selectimage) {
$row = mysql_fetch_array($selectimage);
if ($row) { // check if the image really exists
header("Content-type:image/jpeg");
echo $row["Image"];
}
}

Answer 3

Use a foreach loop to loop through the requested records and echo them out independently to the img tags which your using.
That would be the best way in my opinion.

If you want to display number of different images using one script, try to add some unique hash to the script name ( for e.g. md5( microtime() ) )
$seed = md5( microtime() );
echo '<image src="Image.php' . $seed . '">';
