How to Display Images Stored as BLOBs in MySQL within HTML?

Displaying Images from MySQL Database in HTML

Problem Statement:
Users seeking guidance on retrieving and displaying images stored in a MySQL database as BLOB columns within HTML elements face challenges involving the $result variable in PHP.

Solution:

Directly accessing $result in HTML is not feasible. Instead, an additional PHP script is required to extract the image data and present it.

Modified PHP Script (catalog.php):

<body>
<img src="getImage.php?id=1" width="175" height="200" />
</body>

Copy after login

Image Retrieval Script (getImage.php):

$link = mysqli_connect("localhost", "root", "", "dvddb");
$sql = "SELECT dvdimage FROM dvd WHERE>

Copy after login

How It Works:

The modified catalog.php creates an image tag with a source pointing to getImage.php and specifies the desired dimensions.

getImage.php establishes a MySQL connection, executes the query to retrieve the image data, and extracts the image column into $image.

Subsequently, it sets the header content type to "image/jpeg" and outputs the image data, allowing it to be displayed in the HTML image tag.
