techno-crisis

I'm having a little blogger crisis over here.  After 3 years of blogging, I've maxed out my g**gle photo storage space.  So I'm trying to figure out how to get more and how much more??  Looks like the only way is to cough up a little dough.  I really prefer not to do this, but it would be nice to have an online "back-up" for photo storage.  Sorting through all of the options...any suggestions or advice on how to keep blogging for free (or for very little?)
