idea...i m a mac user and i cant see avi format.....sometimes other formats like quick time works good if you got dream weaver this software help and let you contorl this format i use to change myu format in gif files works good and any html user can see this format.... the link to your file its very simple if you open a folder with this file like http://www.angelfire.com/tx3/onedug/movie/myanimation.avi or myanimation.zip this way the user can open with their browser if they got a newer version you see a warning that tell you if you want to do the download or just the download start....good luck
