I don't have any further suggestions past what Conniekat8 said, but just a note.  Your "little" 450kb texture will not seem so little to P6.  The JPG size makes no difference except how much space it takes up on your HD.  In Poser it will take up as much memory as a BMP.  A 3000x3000 texture will take about 25.7mb, etc.
