Checking

[Ellisyun]

Is my signature working or do u just see the url?

url.. theres a sig check thread in the newbie section

Yup I believe there's a sig check thread for u to check your sig.

To post image or put a image into ur sig, you must go to imageshack or other image hosting websites to host your image first.

No.
You messed up the image tags and HTML tags don't work in sigs.
Here is a full list of all tags you can use: http://serebiiforums.com/misc.php?do=bbcode

There is a preview button for your sig, so there is no need to post to see whether it's working.
This is also the wrong forum btw.
