On the original TDP, the doll builder had an adjustable build area that automatically saved your doll as a transparent JPEG or PNG. Because I don't have access to TDP's builder script, I'm using a less intuitive script that does not have its own save function. If you want to save your doll, hit the print screen (PrtSc) button on your keyboard, paste the screenshot onto MSPaint or a similar program and crop the image downt to just the doll. You will need a program like Photoshop in order to make the backgrond transparent.
