Correct syntax for subdirectories

If I have a site with a directory structure that looks like this:
\public_html
\Images
\test
\Images

What should the correct syntax be if I want to access an image in the "Images" directory? If I login to "Site\test", can I just use ".\Images\File_name"? Will this find the file in the "public_html\Images" or the file in "public_html\test\Images"?

A slash at the front of the path will go to the root directory. No slash will be relative to the current working directory. A dot-slash will go up one directory. So a script in public_html/test would use something like $path = './images'; to get to the images directory that is above the test directory, and would use $path = 'images'; to get to the images below the test directory.

However, because of the way the directories are structured in the question, $path = '/images'; would have the same effect as ./images

Just so I get this correct. If I'm in the "public_html", "Images/.." gets me the file in the root. If I'm in "public_html/test", "Images/.." gets me the files under the test directory.

You're mixing up a few things. Backslash '\' is only a directory separator in Windows. Most browsers and Linux use the forward slash '/'. And if you are viewing the directories from the browser, then 'public_html' has usually been the web site root directory and you can't go above that in the browser. You can go above that on the server in PHP for example.

I know. My last comment said:

If I'm in the "public_html", "Images/.." gets me the file in the root. If I'm in "public_html/test", "Images/.." gets me the files under the test directory.

Didn't I have the slashes correct?

Depends on where you are viewing it from. Normally from the browser and most PHP pages, you can't address 'public_html', it is assumed to be the root of the web site. If you are in 'test', then 'Images' will get the file or directory found in 'test'. If you want the 'Images' in the web root then you use '/Images'.

Got it. Just use "Images/.." This would get me the images from the subdirectory in whatever directory I'm in.

Yes, I believe that is correct and what I would normally do.
