Lost images...

[icculus]

So https://wiki.libsdl.org/Tutorials-TextInput used to have images in its table, like in the Wayback copy:

https://web.archive.org/web/20210119211834/https://wiki.libsdl.org/Tutorials/TextInput

We can link to images from any URL, but we should figure out how to make static images serve from the wiki server itself, so we don't have to rely on other services staying up, and more importantly, so we can have them land in the offline HTML archive, so they're available if someone downloads the HTML to view later without internet access.

This is likely going to need at least small enhancements to ghwikipp, but we can probably mostly cheat on storage by just committing image files to the sdlwiki repository in some way that works for both serving live pages and generating offline mode. We aren't likely to need a lot of images across the entire wiki, and probably all of them will be small.
