After import OAM with Dreamweaver, folders animation_asset is automatically create, inside folder toto and inside toto.hyperesours

in folder toto, i don’t need large image = Default.png
in folder toto.hyperesours, i don’t need large image = image_2x.jpg

I don’t want these images automatically created.
How to do ?

thank you (sorry for my bad English)

Those images can be safely deleted if you don’t use them. They are part of the OAM / Widget specificification and are used as the ‘icon’ in some implementations. They also sometimes appear as a sort of loading screen for some implementations.
