Yes Rad is right Dwight.....What I do is render large my characters in Poser like 1000 to 1600 in Poser with no background imported...I than save and open the file in Photoshop and do one of two things either open the background image I want to use and copy paste the poser image into it as a layer or click on the poser background and paste everything from the background image into the poser image.....then when done with the post work I try to resize it down without losing too much detail for viewing....;)
