bash script read input and feh

I was trying to make a quick script to organize some pictures using feh to display the picture in question and then using bash to read a character from the keyboard and move to a folder based on that letter. Problem is it opens every image in the folder at the start (which is overwhelming). I want to go image by image.

heres the simplified script. There would be different if statements for each letter/dir pair

#!/bin/bash

ls | while read file1; do        #while loop over all images in the dir

feh $file1 &                   
read ch1
if [[ $ch1 == "e" ]]
then
        mv $file1 /PATH/hawaii
        echo "moving to hawaii"
        pkill feh
fi

Problem seems to be that the script doesn't wait to receive the input $ch1 before moving on to the next iteration of the loop. Except that when I do something simpler like the following it does seem to wait on the input

while
echo '1'
read ch1
echo '2'
echo '3'

for f in *; do $(feh $f)&  read g; if [[ "$g" == "e" ]]; then mv -v $f ../tested; fi;pkill feh;  done;

waits for me to enter something before checking whether to move the image and closing the image and moving to the next.

So in a script it would be

#!/bin/bash
for f in *; do
    $(feh $f)&  read g
     if [[ "$g" == "e" ]]; then
          mv -v $f ../tested
     fi
     pkill feh
done
exit 0

indentations ftw
