Shrink large images to at most 1024x1024 pixels

Looks for files over 300k, with current height or width over 2000 pixels,
and resizes those to up to 1024x1024. Uses ImageMagick:

$ find . -type f -size +300k -exec file \{\} \;| awk -F: '{if ($2 ~/image/) print $1}'| while IFS= read -r file_path; do if (( $(identify -ping -format '%w' "$file_path") > 2000 )) || (( $(identify -ping -format '%h' "$file_path") > 2000 )); then identify -ping -format '%w %h %f' "$file_path";echo;mogrify -resize 1024x1024\> "$file_path";fi;done

(Should really ignore the SVG files)

Based on earlier suggestion by Bastian.
