As you're already using the url helper I suggest wrapping your image src attributes with base_url, such as:
由于您已经在使用 url 助手，我建议您使用 base_url 包装您的图像 src 属性，例如：
<img src="<?php echo base_url('images/1.jpg'); ?>" />
And as mentioned in the other answer it's best (mandatory?) to capitalize the class name in your controller
正如另一个答案中提到的那样，最好（强制？）将控制器中的类名大写
class Caller extends CI_Controller { ...
回答by Kenzo
First of all, you need to capitalize your class name.
首先，您需要大写您的班级名称。
class Caller extends CI_Controller {
public function index()
{
// method code goes here
}
}
Then, you need to link to those images with absolute links or with the CI URL helper: "/images/1.jpg" and so on. How to use with the CI URL helper is detailed here: Helper
然后，您需要使用绝对链接或 CI URL helper 链接到这些图像：“/images/1.jpg”等。 此处详细介绍了如何与 CI URL 助手一起使用：Helper
EDIT

Load the URL helper with this in your constructor method:
在构造函数方法中使用此加载 URL 助手：
$this->load->helper('url');
You can create a URL like this:
您可以像这样创建一个 URL：
echo base_url("blog/post/123");
That will make:
这将使：
http://example.com/index.php/news/local/123
Or
或者
http://example.com/news/local/123
If you've taken out the index.php in your config file.
如果您已经删除了配置文件中的 index.php。
Here's a class with the constructor that calls the URL helper:
这是一个带有调用 URL 助手的构造函数的类：
class Caller extends CI_Controller {
public function __construct()
{
parent::__construct();
$this->load->helper('url');
}
public function index()
{
// method code goes here
}
}

You can do the same for as you did to Load the CSS files.
Create a folder in Root Directory. Create a sub folder(if you have Multisite)
then point your base_url in config file to your base path.
您可以执行与加载 CSS 文件相同的操作。
在根目录中创建一个文件夹。创建一个子文件夹（如果您有 Multisite），
然后将配置文件中的 base_url 指向您的基本路径。
and then do the same<img id="image1" src="<?PHP echo base_url(); ?>images/[sub-folder]/1.jpg" />
然后做同样的事情<img id="image1" src="<?PHP echo base_url(); ?>images/[sub-folder]/1.jpg" />
回答by Daxen

Make folder in root directory and code easily in views html file.
在根目录中创建文件夹并在视图 html 文件中轻松编写代码。
if directory name is directoryName and image name imageName.jpg
如果目录名称是 directoryName 和图像名称 imageName.jpg
you can call like this.
你可以这样打电话。
<img src="directoryName/imageName.jpg">
