I'm not going to spell the whole thing out due to lack of time, but basically you would use one of the mx.graphics.codec.* classes to encode your image as a ByteArray, and then stick the ByteArray in some kind of LSO, assuming that it is small enough.

Thanks for the tip. I like how you compressed the data before writing to the LSO.

It's not so much of a hack in their case because the contains actual rich text, not garbage.

The approach I've considered is putting focus on an off-stage TextField and populating and selecting its contents with some app-specific serialized data. Whenever that text is changed (due to a paste) it deserializes and updates the app. It's a hack and clutters your real clipboard with garbage. Just not as nicely packaged as this SO approach. well done. Smart, an excellent idea!
