Local presentation online slide show with Thai narration

Online presentation is one of the most creative online applications which require high speed internet connection. The presentation can stream the sound with the slide show so that the visitor can learn the product online cross the world. However, Wiziq.com is provided the service of LIVE online presentation also, but I have not tried to set the live presentation up.
If you would like to present the product like ‘Zero’ yarn, you can create Powerpoint file (PPT) and then just simply go to WizIQ.com or Authorstream.com. Register and upload your presentation on website and that’s it! Your presentation now goes live.
However, for Thai font and maybe other font that is not written in English, you have to use only Tahoma to make sure that the size of the font will not be resized when your presentation file is converted to SWF.(flash) .
For English font for presentation should not have the font size problem.
Presentation shown in this page is Thai version. I will create the English version soon. ( I guess the narrator will be Mr.Roger.)

A presentation file in Thai has been uploaded.
