    JavaScript is client side language. it not allowed to access file to server, if you are using ASP.net then use below line of code for get count of file.

    IO.Directory.GetFiles("\translated\path","27_*.jpg").Count()

    I didn't tried yet, but could be like this.

    $.ajax({
        url: "/images-folder-on-server/",
        success: function (data) {
            var image_count = $(data).length();     
        }
    });

    If the server is Apache and Directory Listing is allowed, and you AJAX' a directory, Apache will typically return a document with a <table> containing the files in the directory if there is no index files present. You can extract the <table> from the document and show it, or count the number of rows in the table containing file information. I would consider any row in that table having a size column with value 0 or higher as a file.

    markup :

    <div id="fileCount"></div>
    <div id="files"></div>
    

    ajax:

    $.ajax({
        url: "images/",
        success: function(data) {
            var parser = new DOMParser(),
                doc = parser.parseFromString(data, 'text/html');
    
            //output the file table
            $("#files").append(doc.querySelector('table').outerHTML);
    
            //or return the number of files
            //tr = icon, filename, date, size, desc
            //consider all rows with a size value holding a number as a vlid file
            var fileCount = 0,
                rows = doc.querySelector('table').querySelectorAll('tr');
    
            for (var i=0;i<rows.length;i++) {
                if (rows[i].children[3]) {
                    if (parseInt(rows[i].children[3].innerText)>0) fileCount++;         
                }
            }
            $("#fileCount").text(fileCount+' files');
        }
    });
