How to retrive Images from database using Jquery

How to retrive Images from database using Jquery

I'm kind stuck on this. My situation: I have a Oracle database with a table where I store images (the file name,albumid, the mimetype of every file and the binary data in a BLOB plus a unique ID). Now what I'd like to achieve is to load all image from the database using AJAX and the GET method. Viewing a specific image using the plugin, AJAX uses the returned data to fill an <ul> somewhere in the document, and that would be the freshly-loaded image.

Alright here's some code:
  1. $(window).load(function()
                    {
                    $.ajax({
                       type: "GET",
                        url: "RetriveIm",
                        dataType: "json",
                        success: function( data, textStatus, jqXHR)
                        {
                            if(data.success)
                              {
                               
                                alert(console.log(data.imageInfo.name));
                                 var items = [];
                                   $.each(data, function(i, item)
                                {
                                  items.push('<li><a href="#"><img src=data:image/png;base64,'+ item.imageInfo.thumbarray +' data-large=data:image/png;base64,' + item.imageInfo.fullarray + ' data-description=' + item.imageInfo.disc + ' alt=' + item.imageInfo.name + ' data-id='+ item.imageInfo.imageid +'/></a></li>');  // close each()
                                  $('ul.es-carousel').append( items.join('') );
                                 });
                               };
                          },
                     error: function(jqXHR, textStatus, errorThrown)
                      {
                         alert("error"+errorThrown);
                         console.log("Something really bad happened " + textStatus);
                      },
                      });      
                     });
