Why Differences There In .html File On Local Host And .html File Uploaded On Web?

index.html

If your kristen stewart's file name is kristen-stewart.jpg then call it by kristen-stewart.jpg not kRIsten-stewart.jpg.

Then /4. Codes/HTML/hosted2/Mel robbins.jpg is not an absolute path. An absolute path will be (for example) https://yourdomainname.com/yourimage.jpg. So maybe consider relative path or a valide absolute path.

Note: Add "./" at the beginning of your src to use the same folder and "../" to move to the upper folder.
