Opacity would fade in the image as a whole, rather than adjusting its brightness/contrast (which is more what gamma would adjust).
I don't know how fancy you want to get, but you could absolutely position a div in front of the image, set for white (or black) and adjust its opacity from 0 to some small percentage (10%, maybe?) as a highlight. jQuery.fn.gammaGlow = function(color,opacity){ return this.each(function(i){ var img = $(this); var css = $.extend({ display:'none', position:'absolute', backgroundColor:color, opacity:opacity, width:img.width(), height:img.height() },img.position()) $('<div></div>') .css(css) .insertAfter(img) .fadeIn() .fadeOut(function(){$(this).remove();}) }); }; -----Original Message----- From: jquery-en@googlegroups.com [mailto:[EMAIL PROTECTED] On Behalf Of Andy Matthews Sent: Monday, November 24, 2008 1:34 PM To: jquery-en@googlegroups.com Subject: [jQuery] Re: How can i do Image rollover with simple gamma change? Yes... You can use the animate method to fade in/out any element by applying opacity. andy -----Original Message----- From: jquery-en@googlegroups.com [mailto:[EMAIL PROTECTED] On Behalf Of expat101 Sent: Monday, November 24, 2008 3:04 PM To: jQuery (English) Subject: [jQuery] How can i do Image rollover with simple gamma change?
