Ho un problema con resize in ambito ARUBA:
Sto utilizzando una routine asp di ResizeImage scaricata dal sito CICONET. Funziona egregiamente sul mio server, ma quando vado su ARUBA non fa assolutamente il resize (3 file) ma mi prende solamente il primo e lo scarica con le dimensioni originali.
Allego il codice di Resize ed anche il mio:

'Sum less significant byte to more significant byte
