THIS is is how you convert files

convert jpg to webp

for i in find . -type f ! -name "*.webp" -name "*.jpg"; do echo $i; if [ -f ${i%.}.webp ]; then continue; fi; convert $i ${i%.}.webp; done

make thumbnails

for i in find . -type f ! -name "*-thumb.jpg" -name "*.jpg"; do echo $i; if [ -f ${i%.}-thumb.jpg ]; then continue; fi; convert $i -resize 352x352 ${i%.}-thumb.jpg; done

then delete jpg

THIS MAKES THE THUMB NAMES
