> how to “add a string” to an image?

Just pinging in, there is a standard way to add almost any information to images: in their metadata. A related effort was discussed in [this post](https://discourse.julialang.org/t/programmatic-image-tagging/6581). So for an actual image, yea you can add a string (among other things). But this is a specific solution for images, maybe a more general solution (like the TOML idea of @kevbonham) is better.
