 * Hi
 * I am having problems with uplaoding images via zip files. I am using wordpress
   3.3 and I get an a failure message when creating Thumbnails.
 * Ok the thumbnails work. Now I get this when I upload a new gallery in a zip..
 * IMG_4856.jpg (Error : Unknown file format)
 * Never used to get these problems. And also the its still saying the wp_head()
   is missing when its in the header.php for the theme.
 * See this other thread for more info
