But if you want to store small banner, or small picture for link to your blog/website, is it must be there too ?
I think, we don't need to store there if only for small banner or icon. The easy way is store in Blogger.
You just post the new page (not new post).
At this post (page post) you can upload many pictures, publish, open the page and you will get the link for each picture.
It is Easy and Free.
