Pcmanfm thumbnailer keep recreating thumbnails

Hello, I wrote a little shell script to handle cbz/cbr thumbnails in Pcmanfm instead of using Evince and every GNOME thing coming with it. The thumbnails are created and can be used normally BUT they seem to be deleted and recreated each time I come across them.

Here's the script:

#!/bin/sh
#cbz cbr thumbnailer made to be used this way: cbz_thumbnailer.sh input (%i) size (%s) output (%o)
#dependencies: unzip unrar file imagemagick awk

TMP_FILE="/tmp/cbz_thumbnailer_tmp"
LOG_FILE="/tmp/cbz_thumbnailer.log"

if [ ! -e "$3" ]
then
	echo "$3 doesn't exist" >> $LOG_FILE
else
	echo "$3 already exist" >> $LOG_FILE
	exit 1
fi

case $(file -b --mime-type "$1") in
	application/zip )
		FIRST_IMAGE="$(unzip -l "$1" | awk 'NR==4 {print $4}')"
		[ "$FIRST_IMAGE" = "" ] && echo "$1 is empty" >> $LOG_FILE && exit 1
		unzip -p "$1" "$FIRST_IMAGE" > $TMP_FILE
		;;
	application/x-rar )
		FIRST_IMAGE="$(unrar lb "$1" | awk 'NR==1')"
		unrar p -inul "$1" "$FIRST_IMAGE" > $TMP_FILE
		;;
	* )
		echo "$1 is not a zip nor a rar file" >> $LOG_FILE
		exit 1
		;;
esac

case $(file -b --mime-type $TMP_FILE) in
	image/png | image/jpeg )
		convert -define jpeg:size='512x512' $TMP_FILE -thumbnail "$2x$2" "$3"
		;;
		
	* )
		echo "The first file of $1 isn't an image (png/jpeg)" >> $LOG_FILE
		exit 1
		;;
esac

rm "$TMP_FILE"

And here's the file in /usr/share/thumbnailers:

[Thumbnailer Entry]
TryExec=cbz_cbr_thumbnailer.sh
Exec=cbz_cbr_thumbnailer.sh %i %s %o
MimeType=application/x-cbz;application/x-cbr;

I'm pretty confused right now, and maybe there's a dumb error. Thanks for your attention.
