Ciao a tutti, sto cercando di capire come risolvere un problema, ma purtroppo non mastico php, ho preso questo tutorial: http://www.atwebresults.com/php_ajax_image_upload/
praticamente upload con preview, ma quando metto in locale il tutto, mi da errore alla riga 17 e 131 anche se nella cartella scarica l'immagine uplodata, non vedo alcuna preview c'è qualcuno che può aiutarmi?
Vi posto il codice ed il sito dove ho prelevato il pacchetto zip.....
