html - how to have more secure urls?

Question

when I am using img tag to show the images, I am using ../images/1.jpg address therefore when users have a look at the source code may easily change the address to /images and see all the pictures. What should I do? or which type of formatting should I use to avoid this, so they do not find the name or actual address of the pictures folder.

 www.example.com/images/1.jpg

Answer 1

Turn off directory listings in your httpd.conf, and in your images directory, create a blank file called index.html.

Also, instead of naming your images something guessable, you could concatenate the image id with a secret string and use a hashing algorithm on it.

Answer 2

如上所述，拒绝目录列表和/或根据参数从 JSP 页面提供目录列表以识别您想要的图像。
