As suggested, that would mean that you could apply your own custom TypeConverter to that property. My thought was to use a base-64 String but I guess any String representation could be used, as Sitten Spynne suggested. Apologies for the partially incorrect information but, in my defence, most of what I posted earlier was news to me and I only got that specific information from the documentation after reading your question. If you want to learn with so many exclamation marks, you probably ought to be doing that reading yourself.
To be fair, the thought of pasting the Base64 representation of the average image into the code is hideous enough to give me pause. I think I'd try the Embedded Resource approach, myself, but I've had bad experiences with that too.
