I want to disable the "save image" menu in mobile web applications that appears when you hold down a finger on an image. I tried the CSS properties:

```
-webkit-user-select: none;
-webkit-touch-callout: none;

```

With "-webkit-user-select" the copy menu is disabled but not the one for saving images. "-webkit-touch-callout" seems not to be working (tried on iPad2).

I also tried this javascript:

```
$('img').live('touchstart,touchmove,touchend', function() {
  event.preventDefault();
});

```

But without any effect.

Any suggestions?
Thanks in advance!
