How to uncheck "Add as a new version to existing files" inside the "Add a document" dialog

Question

I am working on a publishing site collection using the enterprise wiki template. Currently when users want to insert an image inside the rich text editor, they will be prompted with the following:-
And if the user insert a picture that already exists then it will replace the existing one, which might cause the picture to be displayed inside a Wiki page which it does not belong to !!
So is there a way to do any of the following:-
Give the new picture a unique auto generated name?
To un-check the   “Add as a new version to existing files” by default?
Or to always prevent replacing images, as this can cause many conflicts !!
Can anyone advice ?please?
