Is it recommended to store image data in a separate table when working with a large number of text ads in a PHP application?

When working with a large number of text ads in a PHP application, it is recommended to store image data in a separate table to optimize performance and improve data organization. By storing image data separately, you can reduce the size of the main table containing text ads and improve database efficiency when querying or updating records. 

// Create a separate table for image data
CREATE TABLE images (
    id INT PRIMARY KEY,
    ad_id INT,
    image_url VARCHAR(255)
);

// Update the main table containing text ads to reference the image data
ALTER TABLE text_ads ADD COLUMN image_id INT;

// When inserting a new text ad with an image, first insert the image data into the images table
// Then, insert the text ad with the corresponding image_id
INSERT INTO images (ad_id, image_url) VALUES (1, 'example.jpg');
INSERT INTO text_ads (title, content, image_id) VALUES ('Example Ad', 'Lorem ipsum', LAST_INSERT_ID());
