Do NOT upload your files to a website. Do it on your own pc.
This is one of the best official programs used, free for 30 days then you're done. I got my start using this, it DOES allow you to view files from multiple mri discs and/or folders on pc, so learn it, get help from drop down menu in program. I have printed how to's for my dr's to do the 3D cool stuff so get it, i'll post how.
