I've been complaining in my blog about Chromebook not being fit for photography. And by all means I am not a professional, so this is from the perspective of an amature, for fun photographer.
I started a new workflow. I upload my images to Google Drive, then I add a prefix to the file name, usually a -up, for upload. I then open these pictures up in Picmonkey. I add a watermark, and I resize it for the web, no need for a full blown 16 Megapixel image for a blog. Then I upload to my PhotoBlog. I have other blogs on blogger as well, that I am experimenting with to find out what works best for me. Personally I find WordPress more powerful than blogger, but that's my opinion. I also have a SmugMug account where I upload images, better for sharing than Google+ or drive, but doesn't integrate into my workflow like google drive. You just can't have it all :)
So far I am really happy with my Chromebook, which is causing me this headache with photo workflows. I plan to upgrade to a new one in a year or two. I would definitely get one with 4GB or RAM as I feel the pain when I have too many tabs open. I knew this C720 isn't the top of the line, but it works fine with me. I enjoy using it , it fits the bill perfectly for my home use.
Until I find a workflow that fits/works for me I'll keep searching and trying new ways, methods to work with my pictures.
