You make this sound trivial, but I did this (not with a blog per se, but with a silly one-shot parody website I made for fun) and the first time it got posted on HN it exceeded my hosts bandwidth limits in the first hour despite only having a handful of images. Unless you never write anything popular, you at least need a static host like github pages or a cdn or something behind it.

No, you just need a host that doesn't have ridiculously small limits. You can easily find find hosts with limits in hundreds of GB, or TB, or even unmetered. You can find them for free, and you can find them for quite cheap compared to most technologists' incomes.
Were each image 1 MB? My rule of thumb is to have smaller pictures in the page and to link to their full size if needs be. If your webpage exceed a ebook in size while not having more features, there’s a wrong decision made somewhere.
