How can I get more storage for my images?
Images and photos that are uploaded through Blogger get stored in your Picasa Web Albums, which are part of your Google Account. The number of images you can upload is therefore dependent on the amount of space you are using on Picasa Web Albums. To find out how much space you have available, please see these instructions.
If you would like to purchase more storage space, the Picasa Web Albums help center can tell you how.
