Conversion of png files to jps file format

It doesn't seem likely that you create 3D (stereoscopic) images from just any picture, which means that t is unlikely you can just simply convert a single .png file as .jps pictureAt best, you would need a special set of  several PNGs from which you could create a "3D" like image. This technique usually just moves the background a bit to create 3D feel.
