var d = $.extend(c, b);
function e(s) {
if (typeof console != "undefined" && typeof console.debug != "undefined")
{ console.log(s) } else { alert(s) }
}
if (d.speedView == undefined || d.speedRemove == undefined || d.altAnim == undefined || d.speedTitle == undefined) {
e('speedView: ' + d.speedView);

}
$(this).hover(function () {
$(this).css({ 'z-index': '10' });
$(this).find('img').addClass("hover").stop().animate({ marginTop: '-110px', marginLeft: '-110px', top: '50%', left: '50%', width: '175px', height: '181px', padding: '20px' }, d.speedView);
if (d.altAnim == true) {
var a = $(this).find("img").attr("alt"); if (a.length != 0) {
$(this).prepend('<span class="title">' + a + '</span>');
$('.title').animate({ marginLeft: '-42px', marginTop: '90px' }, d.speedTitle).css({ 'z-index': '10', 'position': 'absolute', 'float': 'left' })
