You could also filter by using FileInfo by comparing to the string of the extension you're looking for.

For example the handler for a file changed event could look like:

void File_Changed(object sender, FileSystemEventArgs e)
{
    FileInfo f = new FileInfo(e.FullPath);

    if (f.Extension.Equals(".jpg") || f.Extension.Equals(".png"))
    {
       //Logic to do whatever it is you're trying to do goes here               
    }
}
