Dear ladies and gentlemen,

I have wrote a image processing program. The program opens images with
Delphi standard component TOpenPictureDialog for viewing thumbnails for the
users. For now, I want to save the images with my own file format and open
it still with TOpenPictureDialog component. But the component will raises
exception when I selected the special files of mine in the dialog. I think
that maybe it is due to it couldn't showing the thumbnail of the special
image files. How can I handle this? Thank you very much.

Best regards.

Xiaoguang
