Problemi con upload di file
Salve ragazzi,
dopo aver studiato ho aggiornato e corretto questo script che effettua l'upload di fotografie, inserendo i dati nel mio db.
Lo provo in localhost e funziona perfettamente anche con le foto di grandi dimensioni, sono riuscito anche ad inserire le istruzioni che effettuano il resize e riducono la qualità per avere file più piccoli, ma ieri l'amara sorpresa:
sul Altervista carica solo i file di piccola dimensione, provando quelli "più pesanti", tipo 3 MB o più lo script non carica nulla.
Mi aiutate a capire dove sbaglio? Grazie
Riporto interamente il file UPLOAD richiamato dal form
Codice PHP:

'image/pjpeg' => 'jpg',
