i came across code that on image loading printed the errorstack _and_ added it 
to a error field in the feature attributes. actually i modified this so the 
errors are still saved but also a message is show to the user to check the 
loaded features for error messages.

but codewise the loading of imagelayers is split into layerloaders loading 
multiple images into one layer (this is where i added the message) and the file 
open load one geoimage into one layer function.

how do you try to load plain jp2? how with an accompanying world file?
