You just go here and upload the new pic for sig or avatar www.reeffrontiers.com/members/iroll253/ Once you go to this link you need to click on "Forum Action" button up by the "whats New" buttom and select Edit Profile there.
For the sig pic you can use the same link that you use for posting pics on your thread from imageshack/photobucket/other and just put that link in your signature. This allows a little bigger pic in the signature. Funny I just did all this myself tonight so it's all fresh in my mind.
Thanks I am going to try a new browser now that you have said that. For some reason safari isn't giving me the option to edit anything. I appreciate it.
