Although Ulead Photo Express is a bit old, it still allows you to combine pictures with the help of built-in features. The first thing to do is to browse to where your pictures are, then select 2 or more pictures and then they'll be automatically added to the working area. You can use the Create button to add effects, transitions and many other graphical enhancements. At the end of the operation, after you have combine all the necessary pictures, use Save or Share to export the content you've just created.
