Hm. No, my Lua knowledge is very small. I can try to patch together something, tho.

It was a full sentence that included those variables. Ultimately, it was meant to indicate that it was the cover of that comic book, and not what was depicted on the cover (whereas, a description of the content would certainly be more effective than just "Textless" on a textless cover).

All that said, I've just been informed that neither galleries nor portable infoboxes support alt-text.
