Okay. Here is your problem: your array appears to have NSString objects in them:

mp3Array=[[NSArray alloc]initWithObjects:@"song",@"song1",@"song2",@"song3",@"song4", nil];

These need to be MPMediaItem objects if you want to be able to retrieve MPMediaItem objects and not NSString objects from the array.

If you declare UIImage *image = nil;, then there is no ivar image. Replace that line with UIImage *image = [[UIImage alloc] init];. Because of that, you will be able to set the image with imagewithSize after the if-statement.
