Just to be different - not saying that this way is better or worse...but it works :o) I frequently do mine in Poser by loading the render either as a background picture - in which case to render you will need to put something in the scene, I use a signiture prop I made up in RDS to sign my work. Or as an alternative, I load a square prop into an empty scene, resize the square to fit the window, and paste the picture to the square as a texture. I need to adjust the lighting and the material settings, with this method. Once all this is done, I select the render options window, uncheck render with shadow, and set the size I want. I render and then save as a jpg at either 90 or 95 %.
