Sometime over the past month or so there were one or more threads on how to do this with the native VFP image control. I think Christof was one of the contributors if you search on this topic.
If you're using VFP 9, the new GDIMAGE class (Win32 GDI+ wrapper) may provide additional features as well. For example I've seen articles/snippets where this class is used to convert groups of images to thumbnails, add watermarks and text annotations to images, etc.
