We want a small shadow Background for every image, to this you can use ImageMagick
In Ubuntu / WSL:
sudo apt install imagemagick
for a single image:
convert myimg.png \( +clone -background black -shadow 55x15+0+5 \) +swap -background none -layers merge +repage myimg_shadowed.png
for an entire folder:
find *.png | xargs -I % convert % \( +clone -background black -shadow 55x15+0+5 \) +swap -background none -layers merge +repage %
