Azwaldo, that’s strange. I downloaded the latest WordPress yesterday (jan 6 2007), and there are only 56 files in my images folder (wp-includes/js/tinymce/themes/advanced/images).
Regardless – I’ve been having this problem for about 2 months. I finally just re-installed the latest version, but that didn’t help. The only thing that has helped was un-checking the “use visual rich editor” box helps. Today! We’ll see what tomorrow brings.
