I know how you feel Katy i panicked when i got an award. If you download it by right clicking onto your comp, and add it to your post that will bring the picture up. I'm sorry i'm not explaining it too well but i'm new to all this too. you'll get there in the end and wish your brother good luck from me.
I think Donna has covered it, Just save the award from the nominating blog to your computer and then upload it as a normal picture to your post. Your cards are lovely - ChrissyX
