img is not displayed in vue

In Vue, we often use the <img> tag to display images. However, sometimes we encounter situations where images cannot be displayed. Below, I'll go over some common reasons and solutions that may prevent images from displaying.

1. Image path error

One of the most common problems is an image path error. If the path we provide is a relative path, then we need to make sure the path is correct. A common practice is to place the image in the public folder and use the following code to display the image:

<img src="/images/example.jpg" alt="example image">

The path here starts with a slash /, Represents an absolute path based on the application root directory. If we use a relative path, for example:

<img src="../images/example.jpg" alt="example image">

This means that the image is located in the images folder under the directory above the current component.

2. Incorrect path case

On Windows systems, the case of paths is usually insensitive, and it can recognize paths with different case. But on Unix systems, paths are case-sensitive. This means that if we mistakenly use uppercase or lowercase letters in the path, then it will not be able to find the file. So make sure the case of the path matches the case of the file name.

3. Image file does not exist

If the file path and case are correct, but we still cannot view the image, the file may not exist. Please make sure that the file actually exists in your application directory.

4. Image format error

The browser only supports specific types of image formats, such as JPEG, PNG, GIF, etc. If the image you provide is in an unsupported format, the browser won't be able to display it. If this happens to you, convert the image to a supported format.

5. Network Issues

Sometimes, network issues may cause images to fail to load. This may be due to unstable network connection, server failure, etc. In this case, we need to make sure our network connection is up and confirm that the requested image server is functioning properly.

6. Other Reasons

There are some other factors that may cause images to fail to load, such as browser cache issues, firewalls, ad blockers, etc. In this case, we need to test the image on different browsers and devices to determine the root cause of the problem.

Summary

The above are some common problems and solutions when images cannot be displayed in Vue. We should pay attention to path case and format issues and check if the file exists. If you've made sure these are correct and you're still having issues, make sure your network connection is stable and try testing on different browsers and devices. Through these methods, we should be able to solve the problem of most images not being displayed.
