You asked how to delete everything except the item that is indicated by the mouse. Other answers here show how to fade out in a hovering element rather than disappearing non-hovering elements ...
Here is the answer that hits the point made in your question.
http://jsfiddle.net/g105b/ecJw8/
$(function() { $("img").mouseover(function() { $("img:not(:hover)").fadeTo("fast", 0.5); }); $("img").mouseout(function() { $("img").fadeTo("fast", 1.0); }); });
