Setting up webfonts is not that hard.Yyou only need .woff and .woff2 nowadays as that covers all current and also most not so current browsers.

https://caniuse.com/#search=woff2
For really older ones, well, there always comes the time that things don't work for them anymore ;-) For those you provide a default font fallback and the general font type like sans-serif or serif.
@Ralf That's probably the wrong printRSSHeaderLink() call in gallery.php. I already made a pull request for the Mutiverse repository to fix that.

Thanks @fretzl merged already! Thanks for Dutch translation too!
@Ralf I'm afraid there is no room for comments in album pages without heavily break the layout. Image page does not exist at all actually, so probably neither open street maps makes much sense. I know, album page is more like a slide show page, that's why I said that this is not a standard theme! :neutral: .
The theme was originally meant to be a presentation for special albums, then I added support for pages, search, news etc, but anyway I would like to preserve album's style.
After the conversation with @acrylian on GitHub, about SEO concerns related to not having a real image.php page, I guess that probably the best solution is to create a proper image page, linked from album through the titles on the thumbnails. This way does not affect album layout at all, and also gives the possibility to implement comments and other image related plugin, like bxslider or Open Street Map. @Ralf, I could also add an option to have comments at the bottom of album pages too.
