After talking with support I was directed to this post, which shows how to upload files directly to Cloudinary, as simple as possible, with "unsigned" method:

$('.upload_field').unsigned_cloudinary_upload("zcudy0uz", 
    { cloud_name:'demo', tags:'browser_uploads' }, 
    { multiple:true }
)
.on('cloudinarydone', function(e, data){
    var opts = { 
        format  : 'jpg',
        width   : 150,
        height  : 100,
        crop    : 'thumb',
        gravity : 'face',
        effect  : 'saturation:50'
    };

    $('.thumbnails').append( $.cloudinary.image(data.result.public_id, opts) )
})
.on('cloudinaryprogress', function(e, data){ 
    var W = Math.round((data.loaded * 100.0) / data.total) // %
    $('.progress_bar').css('width', W + '%'); 
});

I was also given a demo page by a person named "Maor Gariv" who answered my support email.
