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

Question

Here is on the sample page http://jquery.malsup.com/block/ is an example of an overlay message with an image:

$.blockUI({ message: '<h1><img src="busy.gif" /> Just a moment...</h1>' });

But I want to display just an image, so I took out the h1 tag:

$.blockUI({ message: '<img src="busy.gif" />' });

But there is still a background color under my image. How can I remove it?

According with source code of jQuery BlockUI Plugin (v2) it is wrapping the message in an h2 tag

if (title) $m.append('<h1>'+title+'</h1>');
if (message) $m.append('<h2>'+message+'</h2>');

so it looks like there is no way without modification of the source code to pass just an image tag.

I might modify the library source code to introduce a new param like image with a condition:

if (image) $m.append(image);

and than I could declare my image like this:

$.blockUI({ image: '<img src="busy.gif" />' });

Any more ideas?

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.
