Play a flash video using the Flash Video Player application:

   [Browser] <-> [Flash] <-> [FVP] <-> [flash video file]

View images with the Simple Image Viewer application:

   [Browser] <-> [Flash] <-> [SIV] <-> [image files]

The content on the far RHS is non-executable data.

I think you are refering to the Flash application that is loaded
into the Flash plug-in. The FVP is *not* inside each Flash Video
File, in the same way that the SIV is *not* inside each image file.
