Try uploading the signature on another image hosting website such as imageshack or tinypic.

The picture is removed or renamed.

Try to use a different image hoster.

It could also be possible the image was removed so to further avoid the issue , re-upload the picture yourself too an image hosting website.

k thks

the place you're hosting it at requires login to see it, so no one can see it & when your login expires you can't see it yourself

use imgur.com
