Out of Space?

I am out of space for photos.  When I tried to post a picture, Google said I have used up all my storage space and need to buy more.  Linda needs to investigate.  Has anyone else heard of this?  Why is google storing my photos from the blog?  Before she buys more (it's only $5 for 20x the amount she already used up) she wants to find out if she is doing something wrong.  After all, $5 is 12 oz of Sweet Frog Frozen Yogurt!
