I would very much appreciate any information the members might have on how the pages are built that allow one to design while online....for example...a business card. There might be a blank template and the customer uploads text and pictures and sees what the finished product looks like. I have seen them based in flash and javascript..but as of this moment, I don't even know what most developers call this type of page. I have searched many ways to no avail. Also, I believe the company receives the finished information as a PDF file...but I don't even know that.
Thanks in advance for any information on this subject
