Technical Difficulties

For some reason Blogger will not allow me to upload any photos to my blog because I have "used" my 1Gb of free space.  Yet when I go to see about purchasing more space, it says the limits for my current plan, and it says I have used none of what I get for free.  Has anyone had this problem?  I'll start posting again once I solve this problem.  Thanks for any help you can give me.
