[SOLVED] Missing Alt text on images

Hi, I am developing a new site www.coffeeforroses.com with 3.7.13, and wordpress 3.8. Although the image alt tags show up in firebug, meaning the code is there, none of the images when hovered over actually display the alt tag text. The header images are in header widgets so that I can have different versions on each page, but the posts are just regular images and/or featured images. I checked a few of the sites in the showing off thread, and some of them have alt tags that aren't showing up as well. I use firefox, but checked IE and Safari as well. Thanks.
