If you mean the sample image, L7s cannot "fix" this. What you can do is submit an IR on the set (select "Wrong Smple Image" as the type of IR, and explain why the image should be removed. The resolvers have various tools available, and one of those is "Remove Sample Image". Once it's removed, an L8 can select a correct one.
