Quoted from cabal:have you tried to delete the file first then import it again?
name needs to be the same, as dimensions and file type. But i have to admit i have never done it.
maybe recreating the file is better than overwriting, could be a solution.
Yes I have tried!
Of course, same format, same name. I even tried reducing the size of the file so that it is not bigger than the original one and it does not work
