[font=Arial][size=2]Has anyone used the MovieClipLoader Class, e.g. MovieClipLoader.onLoadInit, for MX2004 AS1.0 to ensure access an externally loaded JPEG or SWF’s properties, such as width and height?

As I understand it AS2.0 compiles to AS1.0 so I’m hoping this can be done.

If not, out of the available methods to check bytes loaded vs bytes total, searching on Flash forums returns a lot of styles on this, what is best for all Flash Players and Browsers?

Thanks in Advance.
