Blogger pictures hosting SEO?

Hosting/Uploading images/photos in Blogger template means you get unlimited Bandwidth and top cl up time for loading to that images/photos in to websites or blogger templates. I have seen many webmasters who created so many templates for websites as well Blogger Blogs and hosted all the images into any free hosting server such as imageshack.us and photobucket.com, but all the free hosting servers gives some limited Bandwidth. It may be 1GB or 2GB or more if you are a premium member. So if you reached your Bandwidth limit, then your images can't be shown on your websites or blogger template or if you used photobucket, then after reached your Bandwidth limit your websites or blogs template shows an image which display to your visitors that Bandwidth limit exceed which hearts the health of your sites or blogs which leads as an unprofessional way and if you used any third party blogger template in which some images hosted on free hosting server and if you have enough traffic to your blogger template, then your visitors may be sees an image of Bandwidth limit exceed. If your Blogger blogs have not enough number of visitor then no problem because you may be not reach to your Bandwidth limit exceed, but it doesn't mean that your Blogger blog never receive enough traffic in the future so why not try to give unlimited bandwidth of your blogger images and then doesn't matter that how much traffic you receive.
