If you want to use the control in other VIs, you can save it as a custom 
control by selecting File»Save. After you save the control, you can place it

Importing Graphics
You can import graphics from other programs for use as background 
pictures, as items in ring controls, or parts of other front panel controls. 
Before you use a picture in BridgeVIEW, you must load it into the 
BridgeVIEW clipboard. To load an example of this type of control, 
right-click the front panel and select Controls»Select a Control…, and 
open 
Example\G Examples\General\controls\custom.llb box
.
If you copy an image directly from a paint program to the Windows 
clipboard and then switch to BridgeVIEW, BridgeVIEW automatically 
imports the picture to the BridgeVIEW clipboard. Or you can select 
Edit»Import Picture from File… to import a graphics file into the 
BridgeVIEW clipboard. Once a picture is in the BridgeVIEW clipboard, 
you can paste it as a static picture on your front panel, or you can use the 
Import Picture option of a popup menu, or the Import Picture options in 
the Control Editor. Picture files supported include 
EMF
BMP
, and 
WMF
files.
