How can I display multiple images to repeater ?

I had reference below article.

Then we had created repeater object to display grid data from csv file.

So , When I set OK to result column , I want to display OK image on repeater.

When I set NG to result column , I want to display NG image on repeater.

I had tried set below script to filter.

But it is not good work.

So , Does anyone have the good solution ?

if(!window.my_filter2) window.my_filter2=1;
else {
if(window.my_filter2>= value.length) window.my_filter2=1;
else {window.my_filter2++;} }

if(value[window.my_filter2-1]['Result'] == 'OK'){

return('app/resources/Uploaded/OK.png');

}else if(value[window.my_filter2-1]['Result'] == 'NG'){

return('app/resources/Uploaded/NG.png');
}
