Sorry to keep asking so many questions, but i have noticed with our upload of Welsh landscapes that several different images often have the same file name. Each upload is just replacing the previous file by that name. Is there some way to give each 'version' of the file its own page on commons or would i have to manually identify each one and re-upload with new file names?

here is an example: https://commons.wikimedia.org/wiki/File:Brecon.jpeg

I will simply have to spend time locating and re uploading each one of these files
