How to Resize Sig picture!?

As you can see.. my sig is tiny... I tried to resize the sig code by selecting it and using the "Sizes" option, but the sig is still the same size. I want my signature to be really big and stand out. How can I do this? Thank You So much for the help.

HEY SORRY EVERYONE.. I WAS SOMEHOW ABLE TO FIX MY SIGNATURE SIZE. SORRY FOR THE INCONVENIENCE.

 

Err I don't think you can edit it in the window. There are many online re sizers if you want to do it again.
As for your "sig" thats more of a wallpaper lol. I think those dimensions are too big and might get you in trouble.

Your signature is currently way over the limit..

 

i fixed but im not sure if its still too big. I seen other members with bigger sigs I think.

 

could you make me a sig?
