How do I add a backround

[~ Dākunaitomon ~]

for example say I want to have this image
[img]http://digipedia.db-destiny.net/encyc/images/magnamon.jpg[/img]
and this background [img]http://www.freefoto.com/images/33/15/33_15_15---Fire-Flame-Texture_web.jpg?&k=Fire+%2F+Flame+Texture[/img]
how is it done?

Try using Paint.NET or GIMP. Both are freeware photoshop alternatives.
