How does storing images in a database affect database performance and access speed?

Storing images in a database can significantly impact database performance and access speed because images are typically large files that can slow down queries and increase storage requirements. To improve performance, it is recommended to store images in a file system and store the file path in the database instead. 

// Example code to store image in file system and save file path in database

// Upload image file
$targetDir = "uploads/";
$targetFile = $targetDir . basename($_FILES["image"]["name"]);
move_uploaded_file($_FILES["image"]["tmp_name"], $targetFile);

// Save file path in database
$imagePath = $targetFile;
$query = "INSERT INTO images (image_path) VALUES ('$imagePath')";
$result = mysqli_query($connection, $query);
