Re: FLASH: movie size???

[Ron]

Would several swf files load the same way files in an html document load?

The first one that the client browser reads is the first one that's loaded

and so on? Then as the first file is loaded and playing the others would be

loading simular to using a pre-loader. If .jpeg's or .gif's are used do they

load as part of the .swf file?
