HTML issue...This should be easy right?

Hey Warriors,

I have 2 html files that i'm having an issue with. I created them in Dreamweaver, one as a sales page with images and text and the other as a download page with 2 images,text and PDF links on it. When I saved and moved them to my desktop they worked fine,displayed images and the download links worked. But when I moved the two files to my FTP manager in Filezilla to transfer onto my site, the images on the html files don't display in my browser/browsers and the download links don't work, they give me a 404 error when I click the DL links on those pages too. I don't know what the issue is but this is what I need:


1)For html file #1: I need it to open as a url with all my images and buy button ready to go for my sales page.

Example: www.Mywebsite.com/product.html

I need to be able to upload this html file via FTM/Filezilla to my website as my sales page. Then it can be a working URL.

2)And for HTML file # 2, I need it to be a custom download page URL that displays my images and my download links so people can download my products . I also want to upload the html file via FTM/Filezilla to my site. Or stand alone as its own custom URL.

Ex:
www.CustomURL.html

:confused:
