Explanation
The Picture property sets a background image displayed on the the display area of the thumbnail image (the black portions of the display area) when the thumbnail hasn't been clicked. This property could be used to create the effect of window blinds being opened to reveal a thumbnail image when the mouse is clicked on that thumbnail image frame.
This property is enabled when the Style property is vikCustom. The black RGB(0,0,0) portions of the foreground image is set as a transparent color. The thumbnail image will be displayed through this portion of the background image.
Example:
In C++Builder
VIkThumb1->Picture->LoadFromFile("HalfOpen.bmp");
VIkThumb1->PictureDown->LoadFromFile("FullOpen.bmp");
In Delphi
VIkThumb1.Picture.LoadFromFile('HalfOpen.bmp');
VIkThumb1.PictureDown.LoadFromFile('FullOpen.bmp');
