How to Display MySQL Database Images in an HTML `` Tag?

Displaying Images from MySQL Database in an HTML Image Tag

MySQL allows you to store images in its database using the BLOB column type. However, to display these images in an HTML image tag, you'll need to retrieve them from the database and embed them into your HTML code.

To achieve this, follow these steps:

1. Query the Database

Use MySQL's SELECT statement to retrieve the desired image from the database. The query should specify the table name, the column containing the image (e.g., dvdimage), and the ID of the desired record.

2. Store the Result

The result of the SELECT query will be stored in a PHP variable. However, the variable will not directly contain the image data. Instead, it will contain a resource representing the result set.

3. Handle the Result

You cannot embed the resource representing the result set into HTML. To get the image data, you need to create another PHP script (e.g., getImage.php) to handle the result.

4. Create the Image Handler Script

In the image handler script (getImage.php):

• Establish a database connection.
• Execute the SELECT query to retrieve the image based on the provided ID.
• Fetch the image data from the result set.
• Set the appropriate content-type header (e.g., image/jpeg).
• Output the image data.

5. Modify the Original Page

Once you have created the image handler script, you can modify your original page (catalog.php) to display the image using the src attribute of the img tag:

By using this approach, you can easily retrieve images from a MySQL database and display them in an HTML image tag.
