jason Code [EDITED] :

NSMutableArray* myImages = [[[NSMutableArray alloc] initWithCapacity:607] autorelease];
    for( int i = 1; i <= 607; i++ ) {
        [myImages addObject:[UIImage imageNamed:[NSString stringWithFormat:@"p%d.png",i]]];

Answer 1

// There are actually 51 images in this series (0000-0050)     
NSMutableArray* myImages = [[[NSMutableArray alloc] initWithCapacity:51] autorelease];
for( int i = 0; i <= 50; i++ ) {
  [myImages addObject:[UIImage imageNamed:[NSString stringWithFormat:@"image_%04d.png", i]]?:[NSNull null]];
}

You actually have 51 images, from zero to fifty.

NSMutableArray *myImages = [NSMutableArray arrayWithCapacity:51];
for (NSUInteger idx = 0; idx <= 50; idx++) {
    NSString *filename = [NSString stringWithFormat:"image_%04d.png", idx];
    UIImage *image = [UIImage imageNamed:filename];
    if (image) {
        [myImages addObject:image];
    }
    else {
        NSLog(@"Could not add %@", filename); // could also throw exception, if you want
    }
}
