You can add the the image url to the NSMutableArray as code below..

     NSMutableArray *array = [[NSMutableArray alloc] init];
     NSString *response = [[NSString alloc] initWithContentsOfFile:[[NSBundle mainBundle] pathForResource:@"index1" ofType:@"html"] encoding:NSUTF8StringEncoding error:nil];
  //  NSLog(@"response == %@", response);
   NSString *regexStr = @"<a href=\"([^>]*)\">";
  //NSString *regexStr = @"<A HREF=\"([^>]*)\">";
    NSError *error;
    NSInteger i =0;
 // NSInteger length =0;
    while (i<[response length]) {
           NSRegularExpression *testRegex = [NSRegularExpression regularExpressionWithPattern:regexStr options:NSRegularExpressionCaseInsensitive error:&error];
        if( testRegex == nil ) NSLog( @"Error making regex: %@", error );
            NSTextCheckingResult *result = [testRegex firstMatchInString:response options:0 range:NSMakeRange(i, [response length]-i)];
 //   NSLog(@"result == %@",result);
            NSRange range = [result rangeAtIndex:1];
            if (range.location == 0) {
            break;
        }
        NSString * imageUrl = [response substringWithRange:range];
        if ([imageUrl hasSuffix:@".jpg"] || [imageUrl hasSuffix:@".gif"] || [imageUrl hasSuffix:@".tiff"] || [imageUrl hasSuffix:@".JPG"] || [imageUrl hasSuffix:@".JPEG"] || [imageUrl hasSuffix:@".png"] || [imageUrl hasSuffix:@".PNG"] || [imageUrl hasSuffix:@".GIF"] || [imageUrl hasSuffix:@".TIFF"]) {
       // NSLog(@"%@",imageUrl);
       // imageUrl = [imageUrl stringByReplacingOccurrencesOfString:@"/syneye_Portfolio/" withString:@""];
            [array addObject:imageUrl];
            //[array retain];
        }
        i= range.location;
        //NSLog(@"%i",range.location);
        i=i+range.length;
    }
