Mi è capitato spesso di leggere di persone che volessero visualizzare nel modulo last news una piccola immagine
questo modulo fa proprio questo, inserisce le ultime news con l'immagine inserita nel articolo.
Funziona proprio come lastnews, ma con una piccola differenza.
Lastnews ti permette di settare categorie e sezioni, il suddetto modulo no.
Purtroppo questo utilissimo modulo mi servirebbe proprio con la possibilità di visualizzare le varie categorie e sezioni.
Chiedo quindi ad esperti se secondo loro è fattibile. E se si, imploro di dirmi cosa modificare per ottenere ciò.
Ecco il codice:

Funziona perfettamente anche in joomla cosi com'è.
