Problem with signature don't visible

[alessandro2011]

I would like use this signature:

[URL=http://www.wunderground.com/cgi-bin/findweather/getForecast?query=Florence, IY][IMG]http://weathersticker.wunderground.com/weathersticker/miniWeather09_metric/language/english/global/stations/16170.gif[/IMG][/URL]

that show some data about the weather present on my city update on almost real time as soon i'm connected.
But i can't see it on the preview so, naturally, i can't see it on the forum.
Could be some problem with gif image?
Could be fix?

I don't think the system allows image signatures like that. I can't see how to make it work as a link like that works in a post but not in a signature.

Hi Alessandro :

I'm sorry but it looks like you'll have to come up with a different signature. I think the system may see this as spam and is blocking it.

I wish you a wonderful day

Ok patience.
Thanks.
