Grandpa: In your photobucket album, under the image, there are 4 choices with boxes of code next to them:
Email & IM
Direct Link
HTML Code
IMG Code
Put your mouse in the box next to IMG Code. It should highlight and say Copied. Next go to your TFF profile settings and in the signature area, right click your mouse to paste the code. Click the preview button and you should see your image. If so, then click the Save button. If you need assistance, just let me know.
