為什麼我的圖像未顯示在HTML中？

圖像未顯示通常因文件路徑錯誤、文件名或擴展名不正確、HTML語法問題或瀏覽器緩存導致。 1. 確保src路徑與文件實際位置一致，使用正確的相對路徑；2. 檢查文件名大小寫及擴展名是否完全匹配，並通過直接輸入URL驗證圖片能否加載；3. 核對img標籤語法是否正確，確保無多餘字符且alt屬性值恰當；4. 嘗試強制刷新頁面、清除緩存或使用隱身模式排除緩存干擾。按此順序排查可解決大多數HTML圖片顯示問題。

If your image isn't showing up in HTML, it's usually due to one of a few common issues — most often related to file paths, file names, or basic HTML syntax. Let's break down the typical causes and how to fix them.

1. Check the File Path

One of the most common reasons an image won't load is because the src attribute in your <img src="/static/imghw/default1.png" data-src="https://img.php.cn/upload/article/000/000/000/175363969567928.jpeg" class="lazy" alt="為什麼我的圖像未顯示在HTML中？" > tag points to the wrong location.

• If the image is in the same folder as your HTML file, just use the filename:

  

   <img  src="/static/imghw/default1.png"  data-src="photo.jpg"  class="lazy" alt="為什麼我的圖像未顯示在HTML中？" >

• If it's in a subfolder like "images", include that:

   <img  src="/static/imghw/default1.png"  data-src="images/photo.jpg"  class="lazy" alt="為什麼我的圖像未顯示在HTML中？" >

Make sure the path matches exactly — not Image/photo.jpg if the folder is actually named images .

Also, double-check whether you're using relative paths correctly. If you're linking from a different directory, the browser might not be able to locate the image.

2. Confirm the Image File Name and Extension Are Correct

Even a small typo can prevent an image from loading.

• Double-check capitalization (some servers are case-sensitive)
• Make sure the extension matches the actual file type: .jpg , .png , .gif , etc.
• Don't assume the file has the extension you think — sometimes files appear as “photo.jpg” but are actually “photo.jpg.png” (especially on some operating systems)

Try typing the full image URL directly into your browser to see if it loads. For example:

 file:///your-folder/images/photo.jpg

or if online:

 https://yourwebsite.com/images/photo.jpg

3. Look at the HTML Syntax

Even if everything else looks good, a small mistake in your HTML code can stop the image from displaying.

• Always close the img tag properly (no closing tag needed, but make sure syntax is correct):

   <img src="/static/imghw/default1.png"  data-src="photo.jpg"  class="lazy" alt="My Photo">

• The alt attribute won't make the image show up, but it helps diagnose problems — if you see the alt text instead of the image, the problem is likely with the src .

• Make sure there are no extra spaces or characters in the src value.

4. Browser and Server Caching Issues

Sometimes, even after fixing the issue, the image still doesn't show — especially if you're viewing a local file or working on a live site.

• Try refreshing the page (Ctrl F5 or Cmd Shift R) to bypass cached content.
• If you're uploading to a server, wait a minute and reload again — some hosting platforms take time to update.
• Clear your browser cache or try opening the page in an incognito window.

Basically, start by checking the path and file name, then look at your HTML syntax, and finally rule out caching problems. These four areas cover most image display issues in HTML.
