Help

Wow, I have never had to back track this much on the blog. Summer is halfway gone and we have had a blast these last couple of months. However, I sit down to blog about it and for some reason, blogger won't let me post pictures? It is saying I have exceeded my picasa web limit. Anyone know what this means? I really can't post without a pic to go with it. If anyone can enlighten me on this prob, leave a comment or shoot me an email!
