Making pictures Bigger! (without quality loss)

[midzt]

I remember reading somewhere about some software that can make pictures bigger without much loss in quaility. Does anyone know what I'm talking about and if so any recommendations on which one is the best (if there are a few). Or is it just a waste of time?

Thank You

I was sent this one not too long ago - I suppose it depends how big you want to go!
