Good luck with it and if you ever need any help feel free to give me a shout. I would also be happy to make a signature with your babies in if you like? If you are interested just PM me.
For me, to get pictures in my signature I do this:
1. On the main page near the top there will be something saying 'Quick Links'. Click on that and below you will find it saying 'Edit signature' and from there it should be pretty easy. You need to have your photo's/image hosted somewhere and then all you have to do is add the url link. Its the button with a picture like logo. But if you need any help just yell.
