The image [...] cannot be displayed, because it contains errors If you see this message, then you must have the Skype Firefox add-on installed. I contacted Skype about this and they gave me this link: https://developer.skype.com/SkypeToolbars?action=AttachFile&do=get&target=SkypeFFPlugin.188.8.131.52.exe It's a beta release that they haven't released to the public yet. I post this here because I recently started a Skype Shoutcast and me and a lot of other people who installed Skype were no longer able to view images in Firefox. If you install this beta-release, it will fix the image problem. So if you give someone a link to the Skype download page, make sure to give them this link aswell, because otherwise there is a big change that they are no longer able to view images in Firefox.
