How do I fix my signature?

[ayesquiggle]

With TBT 3.0 my signature pic doesn't show up anymore, as you can see below (just shows [sigpic][/sigpic]) And it seems like the only way to post a pic is with a image URL, and the pic I'm using is just on my desktop. How do I fix it? This could definitely be obvious, I'm not particularly good with stuff like this lol. Thanks in advance!

You can upload the image onto imgur.com. It's free and can host the image for you almost instantly. Upload the image there and right-click, copy image location and paste the URL there.
