Use soft-link instead of copying the current/previous wallpaper in ~/.config/variety/wallpaper

Version of Variety you are using
0.8.12

Is your feature request related to a problem? Please describe.
From what i can understand, the wallpapers inside ~/.config/variety/wallpaper are copies to represent current and previous wallpaper. These copies can leads to unnecessary writes which is bad for SSDs, it is not that major but if it can be prevented, it will be awesome.

Describe the solution you'd like
Instead of using copy command, we should use ln -sf to create a link to the wallpaper.

Ok, i understand now, Auto-rotate the image according to EXIF data was enabled, because of that a new image was being generated from source using image-magik. I turned it off and now only a .txt file appeas which contains path of current image.
