- Add optional directory argument to images_resize_recursive.sh, zip_images_resize_recursive.sh, and new rar2zip_recursive.sh - Remove hardcoded-path wrappers rar2zip_images.sh and rar2zip_incomplete.sh - Fix zip_images_resize.sh: move SCRIPT_DIR to top, change exit 1 to continue on bad output file so remaining files still process - Use MAX_PIXELS variable in images_resize.sh resize argument - Fix zip_images_recursive.sh: replace case-sensitive 7z globs with find -iregex piped via xargs
