loading images from documents directory into an array

I have some jpg images I am saving to the documents directory from camera shots. I want to find all the jpg images in the documents directory and load them into an array so they can be in a overflow view.

Here is my code to find and sort the jpg images in the documents directory.

   NSString *extension = @"jpg";
        NSFileManager *fileManager = [NSFileManager defaultManager];



        NSArray *paths = NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES);
        NSString *documentsDirectory = [paths objectAtIndex:0];

        NSArray *contents = [fileManager contentsOfDirectoryAtPath:documentsDirectory error:nil];  
        NSMutableArray *jpegFiles = [NSMutableArray arrayWithCapacity: [contents count]];

       NSString *filename;
        for (filename in contents)

        {
            if ([[filename pathExtension] isEqualToString:extension]) 
                     {
             [jpegFiles addObject:[UIImage imageNamed:[documentsDirectory stringByAppendingPathComponent:filename]]];


            }
        }

    // Add the coverflow view
    coverflow = [[TKCoverflowView alloc] initWithFrame:CGRectMake(0, 0, 320, 480)];
    coverflow.coverflowDelegate = self;
    coverflow.dataSource = self;
    [self.view addSubview:coverflow];
    [coverflow setNumberOfCovers:6];

- (void) coverflowView:(TKCoverflowView*)coverflowView coverAtIndexWasBroughtToFront:(int)index{
        NSLog(@"Front %d",index);
}

- (TKCoverflowCoverView*) coverflowView:(TKCoverflowView*)coverflowView coverAtIndex:(int)index{


    TKCoverflowCoverView *cover = [coverflowView dequeueReusableCoverView];

    if(cover == nil){
        // Change the covers size here
        cover = [[TKCoverflowCoverView alloc] initWithFrame:CGRectMake(0, 0, 280, 210)]; // 224
        cover.baseline = 200;

    }
    cover.image = [covers objectAtIndex:index % [covers count]];

    return cover;

}

I have tried everything I can think of and nothing works.

It has been suggested that I load each image by getting the path to the image from the array of pathnames, and use the method imageWithContentsOfFile to load the image.

I have looked this up and did searches for how to do this but with no luck. Could someone show me how to do this.

You should do it as below,

if ([[filename pathExtension] isEqualToString:extension]) 
{
     [jpegFiles addObject:[UIImage imageWithContentsOfFile:[documentsDirectory stringByAppendingPathComponent:filename]]];
}
