NSData *imgData = UIImageJPEGRepresentation(YOURIMAGE,1.0);
// Now store the NSData in the defaults for a key
then load it like this
UIImage *image = [UIImage imageWithData:[defaults objectForKey:@"Image"]];

Try This
for(int val=0;val<[imageArray count];val++){
// imageArray is an Array which contains the Image Names
// See below converting the
NSData *imgData = UIImagePNGRepresentation([UIImage imageNamed:[NSString stringWithFormat:@"@%d",[imageArray objectAtIndex]val]]);
//add this `imgData` into dataArray(Which is An NSmutableArray don't forget to Allocate it)
[dataArray addObject:imgData];
//then Store this Array to NSuserDefaults
[[NSUserDefaults standardUserDefaults] setObject:dataArray forKey:@"key"];
}
// the Get the Stored Data Array from NSuserDefaults.
NSMutableArray* storedDataArray=[[NSMutableArray alloc] initWithArray:[[NSUserDefaults standardUserDefaults]objectForKey:@"key"]];
//`storedDataArray` array contains the ImageData(NSData)
//Use it As you want

try this
NSData *dataVal = [NSKeyedArchiver archivedDataWithRootObject:val];
[defaults setObject:dataVal forKey:keyName];
[defaults synchronize];
