This template is intended eventually to replace [[Image:Some file|various|piped|parameters]] when you switch from using an actual file to using a piece of text, such as a Lua-generated div-monster of a figure. Because image handling is complex it may be some time until all parameters are implemented. The link should point somewhere arbitrary; the alt text ... I don't know how alt text is handled. The thumb size should suggest a size to Lua scripts with a special parameter name that they can implement if desired. Perhaps a Procrustean clip should also be enabled. At the moment just a proof of principle is shown...
