So, if you had an image in your signature, you will need to fix it. Go to your profile and click 'edit'.

Under the signature settings you may notice that your image url is incorrect. It might be prefixed with www.blipswitch.net/.../....
or it might have a mission colon (ie: http// instead of http://). Anyways I just thought I would let you know to go ahead and add your image back to your signature if you want to.

Thanks :)
