Question???

I was just going to do yet another catch-up post for September, but I have reached my storage limit on Picassa/Google.  Has anyone else reached their limit on photos?  It suggested that I buy storage for $5+ a year.  Is this what you all are doing, or do I just post too many photos???  I make my collages using Picassa 3 and then just upload them, but if there is a better way, I'd love to hear it.
