jQuery BlockUI Plugin method blockUI how to display just image without any background

By default you got that:

    // styles for the message when blocking; if you wish to disable
    // these and use an external stylesheet then do this in your code:
    // $.blockUI.defaults.css = {};
    css: {
        padding:    0,
        margin:     0,
        width:      '30%',
        top:        '40%',
        left:       '35%',
        textAlign:  'center',
        color:      '#000',
        border:     '3px solid #aaa',
        backgroundColor:'#fff',
        cursor:     'wait'
    },

So if you don't want any of these just do that in your code:

$.blockUI.defaults.css = {};

Or if you want to exclude background and border just go with that insteard:

$.blockUI.defaults.css = { 
            padding: 0,
            margin: 0,
            width: '30%',
            top: '40%',
            left: '35%',
            textAlign: 'center',
            cursor: 'wait'
        };

Basically using that external stylesheet you may specify any css style you want.

This one works perfectly

$.blockUI({ message: '<img src="your.gif" />' ,
css: { width: '4%', border:'0px solid #FFFFFF',cursor:'wait',backgroundColor:'#FFFFFF'},
  overlayCSS:  { backgroundColor: '#FFFFFF',opacity:0.0,cursor:'wait'} 
});
