How can I put form elements into a table and have a submit at the bottom? I'm working on this module and I want it displays a page as follows. 



What I am doing to get that is just displaying a table through theme() and typing out the HTML for the upload. I want the whole page to be seen as a form; the only element that will need changing is the image that's uploaded. I want also a submit button on the bottom to save changes.

One way to solve this would be to put an edit button and have it go to a new page that is just a form and that would work, but I'd prefer to have it on one page. 

What is the best way to do this? Every site I read on is just confusing me more because they are all doing it different; it's not the result I am looking for because not all that is displaying is going to be a form element.
You should use theme_table.
It will help you.
