Blog HELP :)

Why is it saying that I have hit my limit with blog picture storage? I have been blogging for like 1.5 years and there are other people out there that have blogged for years, right? SO why are they asking me to purchase more blog storage? I don't get it. Can someone help me out there???

ps. We have been sick. Sick as dogs.. Here is a sample of what my bed side looks like. And this was after a trashcan refill.

I have lots of pics and updates to post, but this picture thing has me all frazzled. If anyone has any suggestions, let me know. Do I really need to PURCHASE more space??
