There were a couple of other questions about this, but they were asked many years ago, so I thought I'd start a new one.
For a long time, I used Wiki on a Stick to organise my worlds and allow for easy access. That software is no longer supported and doesn't work with more recent browsers. From there, I created my own website through HTML and CSS to function in a similar way. It works well enough, but it's a very slow process to go through all the time.
So, can anyone recommend me either paid or free software that is useful for storing information about different worlds, characters and so on, with an easy way to navigate between them and room for images.
