Render an imported picture

If I understand correctly, I don't think it's capable of directly enhancing pictures like you're asking. I don't have that much experience with rendering in Solidworks, so maybe someone else can prove me wrong, but PhotoView360 is meant to create realistic images of solid models, not to improve the clarity of existing images. If the image you want to enhance is of a solid model, you can increase the pixel density and re-render that model with PhotoView360. However, if you are just wanting to directly enhance a picture, you will probably have to use a different program.
