本地正常的项目板块图片在服务器部分无法加载的异常求助

Hey there! I’ve run into this exact head-scratcher plenty of times—let’s break down the most likely fixes since your code works flawlessly locally but breaks partially on the server:

• 大小写不匹配（最常见 culprit！）
  Linux/Unix servers are case-sensitive, but your local Windows environment isn’t. If your HTML references <img src="projets/02.jpg"> but the file on the server is named 02.JPG or 02.Jpg, the browser will throw a 404 error. Your 1st and 4th images probably got lucky with perfect case matches, while the others didn’t.
  👉 Grab your FTP tool and double-check that every image’s filename on the server matches exactly what’s in your HTML code—capitalization and all.

• File permission misconfigurations
  Servers need specific permissions to let browsers access files. If some of your images have restrictive permissions (like only the server owner can read them), they’ll fail to load.
  👉 Right-click the problematic images in your FTP tool, check their permissions, and set them to 644 (read/write for the owner, read-only for everyone else). Make sure the parent "projets" folder is set to 755 too.

• Incomplete or corrupted uploads
  Sometimes FTP transfers drop out mid-upload, leaving files that look like they’re there but are actually damaged or truncated.
  👉 Compare the file sizes of your local images with the ones on the server. If any don’t match, re-upload those problematic files—slow and steady this time!

• Cache interference
  Your browser might be holding onto old 404 responses, or the server could have a caching layer (like CDN or Nginx cache) serving stale content.
  👉 Force a hard refresh in your browser (Ctrl+Shift+R on Windows, Cmd+Shift+R on Mac) to bypass local cache. If that doesn’t work, check if your server has caching enabled and temporarily disable it for testing.

• Subtle path differences
  Even if your code is identical, the directory structure on the server might differ from your local setup (e.g., you deployed to a subfolder instead of the root).
  👉 Open your browser’s dev tools (F12), go to the "Network" tab, and refresh the page. Look at the request URLs for the failed images—compare them to the working ones to spot any path mismatches.

Start with the case and permission checks first—those are the two most common fixes for this exact scenario!
