I wish to import a jpg background into poser and then pose the character as desired for the background and then delete the background and export only the posed completed character as a psd file.   Is this possible? 

I've tried to import a background image but I can't seem to get the character to pose after it's imported and then I don't know how to delete the background.   Without the specific background that I want the character's posed for it is much too difficult for me to get the correct posing.  

I hope I've made sense what I'm wishing to do and am asking.  I'm still new at poser and have a lot yet to learn.   I don't know how to create props from a jpg background that I could use in poser to pose them nor what program is used to create props like that, even if that is possible to be done as well.
