Mrs.Tink04,
Go to the picture that you have posted on Photobucket. Right click on the picture, go to Properties, and copy the info in the URL address. Then come back to the DIS, go to Edit Signature, click on the little yellow icon that looks like a photo of a mountain range, just above where you type in your signature info. Then a little window will come up and paste the URL address in there. Click 'OK', then Save your Signature. If you go back and look at one of your older posts, you can see if it worked or not, you don't need to post again to check it.
