I can't take it!!!!

Hi

I really need help. I designed a webpage and can upload it as a .zip file with SmartFTP but once its at my file manager I don't know how to open it?

I even used hostdepartments upload manager and uploaded every single file for my site and if I click on one of the files I can see that particular picure or text but I can't get them to shoe up together as a webpage! If I change the name to index.htm the web preview just shows up as the word INDEX and all my files listed in text.

Please please help me!
