How to use the results of an optional FileSearch to populate an ImageControl ImageFile

[kbosland-curtiss-wright]

Question

I would like to optionally display an image if there is a file in a directory next to where the Bootstrapper is run from. I am running a FileSearch and trying to use the results in the ImageFile, but it complains that the result is (null) (it is null, the file is optional so I am testing not having the file there). I have tried to set the variable conditionally to a default if the file is not found, but that is not working. Any help is appreciated, thanks!

simplified code:

Bundle.wxs:
<util:FileSearch Id="LogoFile" Path="[WixBundleOriginalSourceFolder]Logo\Logo.png" Variable="LogoFilePath" />

BootstrapTheme.xml:

Pretty sure the images in the Bootstrapper UI have to be present when the UI is first shown so FileSearch can't be used for this.
