>I am displaying a small jpeg in a standard VFP image control on a form. In vfp7 I could set BackStyle to transparent and have the image appear "masked" - with only the image showing. In vfp9 both transparent and opaque produce the image on a white background the size of the control. Is this a change in vfp9? Is there a workaround?

The JPEG(JPG) format doesn't support transparency. VFP7 incorrectly treated white background in JPEG as transparent. Starting with VFP8 images are rendered using GDI+ Windows API. You can convert your image to GIF or PNG format with transparency.
