It would be good to add the option to delete the compared photo... and add the translation into Spanish.

Thanks for your interest in the App @llavero-ra

Adding the option to delete photos requries full access to the devices storage. This is something I current don't plan to ever add.

Feel free to provide a spanish translation and I will verify and merge it.
