immagini multiple nel db e cartella con thumbline

[javaweb72]

Ciao ragazzi,

perdonatemi se rompo di sabato ma spero che tanti di voi come me siano online a lavorare...

ho un problema che non riesco a risolvere per la gestione multipla delle immagini.

vi spiego meglio....

ho uno script che inserisce nel db il percorso di un file e contemporaneamente lo inserisce anche in una cartella creando sia la thumbiline che l'immagine grande ora ho la necessità di fare in modo che lo script carichi contemporaneamente 4 immagini e nel caso qualcuna manchi la sostituisca con una di default. Posto lo scrit funzionante per un solo file.

tabella database

-- 
-- Struttura della tabella `immagini`
-- 

CREATE TABLE `immagini` (
  `idimmagini` int(11) NOT NULL auto_increment,
  `big` varchar(45) collate latin1_general_ci default NULL,
  `thumbs` varchar(45) collate latin1_general_ci default NULL,
  `rand_name` varchar(45) collate latin1_general_ci default NULL,
  PRIMARY KEY  (`idimmagini`)
);
