In recent years, with the continuous development of the Internet, people have higher and higher requirements for web design and development. In web design, pictures are an indispensable element. However, when using HTML language to write web pages, sometimes pictures cannot be displayed. This will not only affect the aesthetics and user experience of the web page, but may also lead to the inability to transmit information. This article will discuss the reasons and solutions for why HTML images cannot be displayed.

1. Reasons why HTML pictures cannot be displayed

1. Picture path error

HTML uses relative paths or absolute paths to reference pictures. In the process of referencing pictures, it is possible that If the path is filled in incorrectly, the image will not be displayed correctly. The relative path refers to the positional relationship between the directory where the picture is located relative to the HTML file directory, and the absolute path refers to the absolute address where the picture is located. Therefore, when using relative paths, you need to correctly understand the path relationship between HTML files and images, and modify them according to the actual situation. In addition, the use of absolute paths will bring great inconvenience to file migration or deployment, so relative paths are more commonly used.

2. The image format is incorrect

HTML only supports some image formats, such as jpg, gif, png, etc. If images in other formats are referenced in the HTML file, they cannot be displayed. In addition, even the supported image formats need to be selected according to actual needs in specific applications. For example, for images that need to display a transparent effect, the png format should be selected.

3. Image file name error

Sometimes when entering the image name when writing HTML, the image name may be spelled incorrectly. When opening an HTML file with a browser, if the image cannot be loaded, the image cannot be displayed.

4. The server cannot be connected

When using a local server to load images on the network, sometimes the server cannot be connected. At this time, you need to check whether your network connection is normal, or you can log in to the corresponding website to check whether the website is faulty.

5. Picture damage

If the picture file itself is damaged, it cannot be displayed normally. In this case, you need to download a new picture and replace it.

2. Methods to solve the problem that HTML images cannot be displayed

1. Check the image path

When referencing images in HTML files, you should ensure that the path is correct. If you use a relative path, you need to consider the directory structure relationship between the image and the HTML file; if you use an absolute path, you should ensure that the path is correct and cannot be easily changed. When the path is incorrect, you can determine the cause of the error by viewing the error message in the browser console and make modifications according to the specific situation.

2. Confirm the image format

The image format used in the HTML file should be supported by the web page. When choosing an image format, consider the characteristics and application scenarios of the image. For pictures that require transparency, you should use png format; for pictures that require multiple colors and dynamic effects, you can use gif format.

3. Check the image file name

When entering the image name when writing HTML, you should carefully check whether the spelling is correct. If errors are found, they need to be corrected promptly.

4. Check the server connection

When using a local server to load images on the network, if the server cannot be connected, you should check whether the local network connection is normal, or check whether the corresponding website is faulty . If there is a problem with the server, you need to wait for the server to recover or try to use another server.

5. Replace the picture

If the picture file itself is damaged, you need to download a new picture to replace it.

In short, there are many reasons why HTML images cannot be displayed, and they need to be analyzed and solved according to the specific situation. When writing HTML files, pay attention to issues such as path, format, file name, etc. to ensure that images can be displayed normally.
