Thomo's Hole

Thomo’s Hole has been hosted here in WordPress for quite a few years now but is starting to run out of space, especially for photographs. Some solutions are:

1. Go back through previous posts and lower the resolution of the photos – perhaps just do that through the media library (tedious but possible)
2. Take a paid option at WordPress which increases storage
3. Move all the photos out to one of my cloud storage providers and share links from there back to the posts and pages in the Hole
4. Move the Hole to another CMS provider (like blogspot)
5. Move the Hole out to the cloud (Azure, Google, AWS) although these seem a rather expensive option for what is, from my perspective, an unmonetized hobby blog

So, gentle readers, any suggestions? I am at that indecision/planning/pass the beer stage of deciding on what to do.
