After installing the SSL certificate on your website to improve your security, you may notice that some images are not displayed. Do not panic. Read on to correct this.
When you install the SSL certificate, your website address will adjust slightly and even a slight change can cause great damage to your website. Your website will likely have a URL conflict especially since it was programmed to use images in an unsecured "http" protocol.

Now everything should be used over the "https" protocol, which is not always the case.
This means that you need to change all the images and replace the links from the “http” images to “https”. Fortunately, you do not need to identify and singularly modify all the images you have already sent.
You can cause the migration to your database, which is a much simpler solution.

How to manually search and make changes
It is possible to change the links of your images manually on your database, however, be warned: It is easy to make a mistake on your database and completely break your blog.

However, I will show you how to make the change. However, you must be aware of the different dangers that exist with this operation.
I recommend you to use reliable plugins, as it is unlikely that there are errors. However, there are some security measures you should take before making this type of modification to your blog.
The best solution is to make a full backup of your blog (especially from the database). Here is a collection of Some plugins that you can use to make backups of your blog.
The next step will be to access your phpMyAdmin to make the various modifications (From your cPanel). Go to the SQL query tab and enter the following command.
Make sure you understand the query before you run it.
UPDATED wp_posts SET `post_content` = REPLACE (`post_content`, 'src = "http://www.votresite.com', 'src = "https://www.votresite.com');
Make sure to change the address "http://www.yoursite.com" to the current address of your blog, and you can change the "wp" located in the table name to the current prefix of your installation WordPress. If you are using a multisite network, you must use the following code.

UPDATED wp_2_posts SET `post_content` = REPLACE (`post_content`, 'src = "http://www.votresite.com', 'src = "https://www.your-site.com');
Here you will replace the value "2" in the table name "wp_2_posts" with the correct identifier of your website (the subsite in question). You must run this code for each of the websites in your network.

This may not always be necessary, but if your network is configured in such a way to use subfolders without using several different domains, you will probably need to edit the image links as well.
You will also need to run the following query to update the GUID of your images.
UPDATED wp_posts SET `Guid` = REPLACE (`Guid`, 'http://www.votresite.com', 'https://www.votresite.com') WHERE post_type = 'attachment';
Similar to the first example, you must replace the domain name with your current domain name and modify the prefixes of the tables (you must have a minimum knowledge of SQL, so as not to cause a fatal error. You will also need to run the following query on your multisite network.
UPDATE wp_2_posts SET `guid` = REPLACE (` guid`, 'http://www.your-site.com', 'https://www.your-site.com') WHERE post_type = 'attachment';
Remember to change the identifier "2" to that of the sub-site where you want to perform maintenance.
Your images should normally work fine to match your website's new protocol. If that still doesn't work, you'll probably need to try a few times (maybe you missed something in the process).
Also running one query at a time can reduce the risk of errors.
Find & Replace image links with plugins
Using a plugin to search to replace text on your website is much easier than doing things manually. It's also a less risky solution.
I will suggest to you in the following WordPress plugins that will allow you to search and replace your database. While most don't work on the multisite network, you'll be able to install it on each website individually and perform those find-and-replace operations.
1. Better Search Instead
Better Search Replace is one of the plugins on this list which is multisite network compatible. It offers a fairly simple design without too many options to configure, but at the same time it offers the most used options.

Images can cause you a lot of worry when you switch to an SSL secure domain. You can use your "site URL" (the URL of your website) to make changes to the images.
But this change will only count for future images and therefore is not retroactive. The only solution to correct this is to perform replacements on your database.
