Display images from array to UIImageView

I am trying to display images from the array to the uiimageview, but it only shows the last image. Any advise? 

for (int i = 0; i < [fileArr count]; i++) 
{
               NSArray *fileNameArr = [[fileArr objectAtIndex:i] componentsSeparatedByString:@"."];
check=line;
                NSString *msg = [textView.text stringByAppendingString:[NSString stringWithFormat:@"Opening image: %@\n",[fileArr objectAtIndex:i]]];

                [textView performSelectorOnMainThread:@selector(setText:) withObject:msg waitUntilDone:NO];

                line=line+1;

                [image removeFromSuperview];
                [image release];
                image = nil;
                //specify the image path, open the image file with UIImage library
                NSString *imagePath = [NSString stringWithFormat:@"%@/%@",jfn1,[fileArr objectAtIndex:i]];
                NSString *imageFile = [NSHomeDirectory() stringByAppendingPathComponent:imagePath];
                NSString *pathExtension = [imageFile pathExtension];
                NSLog(@"----------------------------");
                NSLog(@"ImageFile: %@\n",imageFile);
                NSLog(@"File Extention: %@\n", pathExtension);
                NSLog(@"Interger value: %i\n",i);

                UIImage *myImage = [UIImage imageWithContentsOfFile:imageFile];
                NSLog(@"Image Width: %f", myImage.size.width);
                NSLog(@"Image height: %f", myImage.size.height);

                image = [[UIImageView alloc] initWithImage:myImage];
                image.contentMode = UIViewContentModeScaleAspectFit;
                [scrollView addSubview:image];

Because you are always 

[image removeFromSuperview];

before you

[scrollView addSubview:image];

in the for loop.

How could it not be only showing the last imageView?
