This also applies to Plain.

In short, you can't preview it locally simply by double-clicking on the index.html file in your OS. The album has to be viewed from a server, either from the internet, or using jAlbum's embedded server.

(I'll update the documentation.)

Found it. The problem is in the Italian language file for the skin. So, if the album is in English, it works, but in Italian it doesn't.

Laza: the skin should be able to handle this, but it can't. It's the apostrophe in this line of the texts_it.properties file:

downloadImage=Scarica l'immagine

There a few other similar occurrences, though it's that first one that's coughing up console errors.

copyright=Diritto d'autore
copyrightNotice=Avviso sul diritto d'autore
...
exposureBias=Distorsione dell'esposizione
...
mainAlbumPage=Pagina principale dell'album
...
backToIndex=Torna alla pagina dell'indice

They behave themselves if the apostrophes are replaced by the HTML entity, '

Tricky for a user to fix this, because the ui.something entries should be left alone. It's only the strings that appear in the finished album that need to be corrected. The skin should pump these strings through a quick replacement utility upon album build.

Thanks, I will fix this ASAP.
