Pictures on your Google blog are hosted by Picasa Web (which is owned by Google), you get 1 big bite full free then you got to pay. I have seen one or two blogs have this issue and i suppose i knew it would happen sooner of later, well today it happened. My photo files are full (about 3,400 images), changing my header pic regularly doesn't help either, so there are a few options.
1) Pay so we can carry on.
2) Delete a load of photos from the Picasa files but if i do they no longer show up on the blog. I have done this for now by deleting all old header photos that are no longer used, this should keep things going for a week or so while i decide the way forward.
3) Host photos another way, you can even do it via Facebook apparently but if your Facebook is anything like as slow as mine 3,000 photos will kill it dead. I need to look into this further, there are probably ways of getting round it if you are aligned to the technical age, i am not that person.
So it looks like if i want to carry on it's no longer a freeby, things will have to change.
In the meantime your support by buying a T shirt would be gratefully received, hit the T shirt pic to the right to take you to the ebay sale.... assuming i haven't deleted it.
