In IE7, this doesn't work on an <img> element (and possibly others, didn't test it):
$(".pics").attr("style","border-style: solid; border-width: 1px; border-color: white;"); But this does work for IE7: $(".pics").css("border-style","solid").css("border-width","1px").css("border-color","white"); Both work in FF2. Is that the expected behavior in IE7? I have an example written up both ways to illustrate. Select one of the small images, its border should change to white: You can see the working version here: <http://www.corry.biz/phototest/> And the non-working version here (requires IE7): <http://www.corry.biz/phototest/phototest2.lasso> - Bil
