Images in Email Templates are not showing up

Today we did realize that images in email templates are not showing up when we use them. I've checked the template definitions and found that they also don't include the images. The images have broken image file icons in their place. This seems to be a recent issue because we were normally using the templates without any problems. We can't exactly tell when this problem started to occur. Please check out and fix this issue as fast as possible because we do depend on the templates to do our work.
