Are there any potential pitfalls to be aware of when storing images as BLOBs in a MySQL database?

One potential pitfall of storing images as BLOBs in a MySQL database is that it can lead to slower performance and increased database size. To mitigate this issue, it is recommended to store the images in a file system and only store the file path in the database. This allows for faster retrieval of images and reduces the size of the database. 

// Example of storing image in file system and saving file path in database

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

// Save file path in database
$image_path = $target_file;
$sql = "INSERT INTO images (image_path) VALUES ('$image_path')";
mysqli_query($conn, $sql);
