I have an image inside a contenteditable container and I have defined some data to this image with:

$('#myImg').data("or_width",100);

I see it working well until I drag and drop the image to another position of the contenteditable, then, the associated data dissapear.

As a workaround, I have defined the data with:

$("#myImg").attr("data-or_width");

With this, I can get the data after move the move, but it is not the best way I think, as that creates a new attribute to the image.
