Sharepoint list add icon to modified item

I am using this caml query to select all items in a sharepoint list that were recently modified. Now I want to add some kind of icon to the title as an identifier that the item was modified. Kind of like the new.png that sharepoint uses.

<Where>
      <Gt>
         <FieldRef Name='Modified' />
         <Value Type='DateTime'>
            <Today Offset='-7' />
         </Value>
      </Gt>
   </Where>

Update: Does anyone have an example of this?

Show Modified in your list view,then select eligible items in csr and add icons.

<script src="http://code.jquery.com/jquery-latest.js" type="text/javascript"></script>
<script>
(function () {
    var overrideCurrentContext = {};
    overrideCurrentContext.Templates = {};
    overrideCurrentContext.OnPostRender = renderItem;
    SPClientTemplates.TemplateManager.RegisterTemplateOverrides(overrideCurrentContext);
})();


function renderItem() {
    
    
        var rows = ctx.ListData.Row;
        for (var i = 0; i < rows.length; i++) {
            var Modified = rows[i]["Modified"];     
                console.log(Modified)
            var SevenDaysAgo=   new Date(new Date().getTime()-24*60*60*1000*7);
            if(SevenDaysAgo.getTime()<new Date(Modified).getTime()){
            var rowId = GenerateIIDForListItem(ctx, rows[i]);
            var row = document.getElementById(rowId);
            $(row).find("td>div[field='LinkTitle']").append("<img src='http://sp/Shared%20Documents/download.png'/>");
            }
            
            
        }

        ctx.skipNextAnimation = true;
    
   
}

</script>
