None of us can understand what you are talking about. Try listing issues briefly in a numbered fashion (for best results):

1. First detailed question here (I want to do this)
2. Second comment here (What I want is this)
3. Third here (Here is an example) .......etc....

Sorry, the source coding on web pages can be viewed, but not changed by anyone outside of the hosted account (the administrator). Your [site] can be hacked, however, if you allow a "door" such as ill-written scripts or other 'portals' to be published on your site.

To allow "uploads' or modifications by Users of your website, you will need to furnish a type of interface, be it a script, a form, or functionality written into the site itself (such as might be featured in a CMS script: forums, photo contributions, memberships, blogs, etc.).
