I have this code for centering vertically the images in a bunch of divs.
function centerImages(parent, image) {
var parent_height = $(image).parent().height(
Try this instead...
function centerImages(image) {
var parent_height = $(image).parent().height();
var image_height = $(image).height();
var top_margin = (parent_height - image_height) / 2;
$(image).css( 'margin-top' , top_margin);
}
$(".clients li img").each(function() {
centerImages(this);
});
You weren't actually passing in images, just the class selector. The above selects all relevant images and passes them in - there's no need for the parent parameter.
