Yes, you have to upload all the x-rays too. From the dentist and chest x-ray. I had no problems scanning with normal scanner, i had my chest x-ray on cd, and it's still seen very good. For the chest x-ray I would go to some place, where they have those big copy machines. I am 100% sure, that they can scan you there, and you will upload it on the portal!
