I prefer to use sprintf() to build the base filename, and then use fullfile() to construct the full file name from the folder and base file name. You're putting your images in the current folder, same as your m-file scripts. The current folder is pwd.
Also, please use better variable names than I (which looks a lot like 1 and l) and J. Use longer, more descriptive names that will help explain what you are trying to do. Also make sure you put comments into your code.

Note that using fullfile is preferred over string concatenation.
