MikeysTown,
Happy anniversary, in order to have your sounds and video files open you simply need to place them on your web server and create links to them,
Example
You have an MP3 file named anniversary.mp3
Upload anniversary.mp3 to your web directory on your server
Place a link to it (
http://www.yoursite.com/anniversary.mp3
When your visitor clicks on it the mp3 file will play.
Since nothing is ever as easy as it seems, here are some things to note.
a. be sure your host allows audio and video files
b. there are a variety of different formats out there, if you're offering a file format that the visitor doesn't have a program to play, he won't be able to play your file.
c. video and audio files can use up a large amnount of data transfer (bandwidth) very quickly specially on a popular site, check with your hosting plan to ensure you have adequate data transfer quotas, I would additionally inquire with your host as to their policies regarding exceeding quotas since that can be costly.
Best of luck to you.
