How do I convert sales page and thank you?

Peeps

I have a sales page with a thank you page with order button but I want to change it so there are two downloads on the page for two separate products.
SO how can I do that please? And change pictures?
I guess I have to name the new picture same as the original and replace?

I also want to put Youtube vids on the pages but I guess that one is easy.

This shouldn't be too hard with a lil bit of html. It depends if you have a dynamic download link though, if you want me to look at the code I should be able to point you in the right direction.

I changed pics however the thank you page is on Clickbank and also the site keeps saying the original site.

I think I have to make a totally new one.
