Using some of the code from the following topic:

Load and display all the images from a folder

You can use a standard way, such as:

// array of supported extensions (use a List if you prefer)
    static final String[] EXTENSIONS = new String[]{
        "gif", "png", "bmp" // and other formats you need
    };
    // filter to identify images based on their extensions
   static final FilenameFilter IMAGE_FILTER = new FilenameFilter() {

    @Override
    public boolean accept(final File dir, final String name) {
        for (final String ext : EXTENSIONS) {
            if (name.endsWith("." + ext)) {
                return (true);
            }
        }
        return (false);
    }
   };

and then use is it as so:

{
    ....
    File dir = new File(dirPath);
    File[] filelist = dir.listFiles(IMAGE_FILTER );
    for (File f : filelist)
    { // do your stuff here }
    ....
 }
