format() comes in handy there:

  for(int i=22; i<24; i++){
      cv::Mat m = cv::imread( cv::format("%d.jpg",i) );
  }

cvLoadImage does not work like printf! If you want to create a string using variables, use a stringstream. Then use the <<-operator to create the string you want.

And don't use the old C interface! Use imread, which expects a string. The stringstream class has a str() method which will give you the string you want.
