Plugin don't see the New files for - "Tasks that specify only "src" files"

[trikon]

imagemin: {
        all: {
            files: [{
                expand: true,
                cwd: 'images/',
                src: '**/*.{gif,png,jpg,jpeg}',
                dest: 'images/'
            }]
        }
    }

After first run(when the cache has been created), the grunt-newer don't see NEW added images in images/ folder:). It sees only changed images... I have such feeling that the plugin is do not stores src's folder files list in plugin's cache...
