One of the "problems" with Image is that it doesn't know how big it is until the image is loaded, which is after the VBox measures and sizes it. It should cause another layout pass after the image loads, but sometimes various constraints and flags prevent that from happening.

These are images which get fed a different source in different states, through a <mx:SetProperty/> (to make a slide show with captions). The above code worked in the starting state (which is not the same as the base state) but then didn't work in subsequent states. I don't understand why that would be the case. I suppose I could insert a <mx:SetProperty/> for the autoLoad and a <mx:SetEventHandler/> for the complete event in each state but there must be a more elegant solution. Thank you very much for your response.
