thinkphp picture cannot be displayed

When using thinkphp to develop websites or applications, we often encounter the problem that images cannot be displayed. This situation usually has the following reasons:

1. The image path is incorrect

2. File permission issues

3. The image format is not supported

4. Picture damage

Then let’s take a look at these causes and corresponding solutions.

1. The image path is incorrect

When using thinkphp, the image path is usually relative to the web root directory. If the image path is written incorrectly, the image will not load correctly. At this point, we need to check whether the image path is correct. The specific method is to use the browser development tool to check whether the address of the image on the page is correct. If it is incorrect, it can be solved by correcting the image path.

2. File permission issues

When we upload an image to the server, the file must have the correct permissions to be displayed correctly on the web page. Therefore, we must ensure that sufficient file permissions are granted when uploading images. Usually, setting the permissions of the picture folder to 755 is enough.

3. Image format not supported

Supported image formats may be different in different web browsers. If your image format is not supported by the browser, it will not be displayed correctly on the website or application. Therefore, it is recommended to use commonly used image formats, such as jpg, png and gif formats.

4. Picture damage

In some cases, even if the format of the picture is correct, it may not be displayed correctly in the browser. For example, if an image file is corrupted, the image cannot be loaded correctly. You can check if the image is visible by opening it or use another image editor to repair the corrupted image.

Summary

The failure to display images on websites or applications is a common problem that can be solved by checking the image path, file permission issues, image format, and image damage. Although solving these problems is relatively simple, it does require patience and some technical knowledge. If you have difficulty doing these, it is recommended that you contact technical support for better assistance.
