        else

We have been using Salesforce Quotes for over six months now and today when I logged in to generate a quote, the images in the text/image field are no longer showing up.  We see the following broken image icons.  I have checked the image (uploaded in documents) and the externally available setting is still checked.  Literally nothing was changed, and the images are no longer working.  Any ideas would be appreciated it!
