Topic: Using EffectsUtil as for DropShadowFilter

I've scoured the internet on this to no avail. Can anyone provide any insight into how to use the file included with the Pro version of AV to add a drop shadow to the photo frames? I'm not sure if this code needs to be copied somewhere else (if so then where?) or the whole file placed in another location. I'm sure this is something many of us would like to do. Thanks to anyone who can help!
