Apart from the (maybe) orkish figures, the rest could be from any fantasy game of the period (Fantasy Warriors?) and the knights likewise.

In your gallery, there is a box on the right with "share" and a whole lot of links. Copy and paste the top one (forums) into your post.
Et voila, the pics are then in your post. Like this.
