Removing Blemishes from Photos

[AndyD]

HI there,
I wondered whether anyone could recommend how I could remove blemishes form photos? I have a sweet photo of my daughter at Halloween but it looks as though she needed her nose blown when the photo was taken... you can imagine what I mean. We'd like to send out the photos to friends and family, any advice greatly appreciated.

Cheers

Andy

PS
Sorry didn't realise image was so big. If there are any complaints or a limit to image sizes please let me know and I'll remove.
