In web development, HTML uses the a1f02c36ba31691bcfe87b2722de723b tag to insert images, which is a common element. But sometimes, when a web page is rendered in a browser, the image may not display correctly. This article will introduce some common problems that may cause HTML images to not be displayed, and how to solve these problems.

  1. Image link error

When using relative paths to reference images, it is easy to encounter image link errors. If the image isn't linked correctly, the browser won't be able to load it. Therefore, you need to check whether the image path is correct. Relative paths should be specified based on the location of the file, not the domain name of the website.

For example, if the image is located in the images folder in the root directory of the website, you can use the following code to insert it into the HTML file:

<img src="images/myimage.jpg" alt="My Image">

If the image location is In the same directory as the current HTML file, you can use the relative path ./, as shown below:

<img src="./myimage.jpg" alt="My Image">

Please note that the case of the image path must also match the actual path. Therefore, if the image file name is "myimage.jpg", the case in the path must match exactly.

  1. The image does not exist or has been deleted

If the image path is correct but the browser still cannot load it, it may be because the image does not exist or has been deleted. In this case, check the image path and make sure the image actually exists at the specified location.

Also, if you are using an external image link, you also need to ensure that the link is valid and that the target server is running.

  1. Image format not supported

HTML supports images in a variety of other file formats, but not all browsers support all file formats. Common image formats include JPEG, PNG and GIF. Therefore, if your image format is not supported, the browser will not be able to load the image correctly.

To solve this problem, it is best to use standard image formats such as JPEG, PNG and GIF. Additionally, you can try converting the image to a supported format to ensure the browser can load it.

  1. Image loading

If your network connection is slow or the image is large, it may take a long time to load the image. In this case, the browser will try to load the image from the server, but will not be able to display the image correctly until the load is complete.

To solve this problem, you may consider using thumbnails to display them in the page before the image is fully loaded. Additionally, you can optimize the size and format of your images to reduce loading times.

  1. Firewall or proxy server issues

Sometimes, the browser cannot load images from the server because a firewall or proxy server blocks the browser's request. In this case, you can try changing your network settings or contact your system administrator to resolve the issue.

  1. JavaScript is disabled

JavaScript is usually used to process images in web pages. If the user disables JavaScript, the image may not be displayed correctly. In this case, to ensure that the image displays correctly, you should ensure that JavaScript is enabled in your browser.

In this article, we introduce some common problems and solutions that may cause HTML images to not display correctly. By checking image links, existence, file formats, loading issues, network settings, and JavaScript, you can resolve issues with HTML images not displaying correctly and ensure your website is functioning properly.
