I've got all my pages and images in one folder "html_public." Question is can I create subfolder ("imiages") in this folder, to which my web page url's would be directed, or must files be in one subfolder.

Wow, What is your native language out of curiosity?

Anyways... I think you said you have your files in the "public_html" folder, and you wanted to know if you create a folder named "images" under that folder (public_html/images) would it be web accessable.. YES...

IF you created "images" inside of "public_html", you can put your pictures etc in that images folder and call them from the html using "/images/file.jpg" etc...
