What are the implications to redirecting images behind the image tag ?

Last Updated : 07 Feb, 2023

This article intends to make the readers understand all possible implications while redirecting images in an HTML document. We will cover the implications as well as approaches to avoid such scenarios and discuss simple examples for a brief illustration as well. Before that, let us go through the <image> tag.

Implications to Redirecting: Redirecting images behind the image tag can have a number of implications, depending on the specifics of the redirect and the context in which it is used. There are several implications to redirecting images behind the <image> tag. Here are a few potential implications to consider while adding an image to an HTML document.

If the redirect is implemented using the src attribute of the <img> tag, it can cause the image to be loaded from a different location than the one specified in the HTML. This might cause the image to be displayed differently, or to not be displayed at all if the redirect fails.
If the redirect is implemented using a server-side language or technology, such as PHP or ASP.NET, it can introduce additional processing overhead and potentially slow down the loading of the image.
If the redirect is implemented in a way that causes the image to be loaded from a different domain, it may result in the image being subject to cross-origin resource sharing (CORS) restrictions. This can prevent the image from being loaded, or cause it to be displayed differently, depending on the CORS policies of the domain from which the image is being loaded.
If the redirect is implemented in a way that causes the image to be loaded from a different domain, it may also result in the image being subject to different security measures or policies, such as content security policies or cross-site scripting (XSS) protections. This can affect the way the image is displayed or handled by the browser.
Often it is observed, that the issue lies on the other end of the situation. This refers to the case where an image is not available or if the user has disabled images in their significant browsers.

How to add an image to an HTML document?

Adding an image in your HTML document, along with avoiding all implications related to the image tag. We’ll discuss some examples with the proper approach, out, and snippet to refer to. Here are the two examples discussed.

Method 1: We will simply add the image in the HTML document with the help of <img> tag. The <img> tag in HTML is used to embed images into a web page. It is a self-closing tag, meaning it does not require a closing tag. To add an image in an HTML document, you can follow these steps:

Create a <img> tag in your HTML document where you want the image to appear.
Add the “src” attribute to the <img> tag, which specifies the location of the image file you want to embed. This can be a relative or absolute URL.
You can also add the “alt” attribute to the <img> tag, which provides alternative text for the image in case the image cannot be displayed. This is important for accessibility.
You can also add the “width” and “height” attributes to the <img> tag to specify the dimensions of the image.
Save your HTML document and open it in a web browser to view the embedded image.

Example: A simple example to illustrate the process of adding an image to an HTML document.

HTML

<!DOCTYPE html> 
<html> 
  
<head> 
    <title>Page Title</title> 
</head> 
  
<body style="text-align:center;"> 
    <b> 
        <h1 style="color: green"> 
              Welcome To GeeksforGeeks! 
         </h1> 
    </b> 
    <img src= 
"https://media.geeksforgeeks.org/wp-content/uploads/20230129110541/technical.png"
         alt="Geeksforgeeks Technical scripter" 
         style="width:200px;height:200px;"> 
    <br> 
    <p>Here, we have simply attached this  
          "Technical Scripter Challenge"  
       Logo as an image in our HTML Document.</p> 
</body> 
  
</html>

Output:

Method 2: We will simply add the image in the HTML document with the help of img tag. In this case, we are supposing that the required image is placed in a different folder than that of the HTML document. In such a case, just putting the image name won’t help or act as an implication in redirecting to the image added. Thus, to sort this out we will give the entire path within the image tag.

HTML

<!DOCTYPE html> 
<html> 
  
<head> 
    <title>Page Title</title>

<body style="text-align:center;"> 
    <b> 
        <h1 style="color: green"> 
              Welcome To GeeksforGeeks! 
         </h1> 
    </b> 
    <img src= 
"https://media.geeksforgeeks.org/wp-content/uploads/20230129110556/gfglogo.png" 
         alt="Geeksforgeeks LOGO"
         style="width:200px;height:200px;"> 
    <br> 
    <p>Here, we have simply attached the GFG logo  
       as an image in our HTML Document.</p> 
</body> 
  
</html>

Output:

Note: While adding static data, like images, videos, gifs, etc. in HTML documents we need to ensure that all the data is present in the same directory. If not, you must give the correct path of the image file or any other type of file to be added.
