[Chameleon] Need help with the ScaleZoom widget

[Blaine Ray]

the "CurrentImage" option doesn't seem to be supported at this time..not
sure if it's because "ScaleZoom" is a BETA widget.

When you use CurrentImage as an option, it doesn't load an image at all,
but rather a blank image placeholder showing alt text.

Hi,
There's CurrentImage="" option in this widget. Does it do the trick?
