What is the best free (no trialwares!) software that can view DICOM
images, from doctors' offices and hospitals, in updated Windows XP Pro
SP3? I only need to view the images.

Googling "dicom file viewer" returns quite a few choices, including
some free ones.

But so many are free to be trialwares only. Many old freewares cannot
seem to open the image files (can't share them in public too).

Allah's Apostle said, "Once while a prophet amongst the prophets was
taking a rest underneath a tree, an ant bit him. He, therefore, ordered
that his luggage be taken away from underneath that tree and then
ordered that the dwelling place of the ants should be set on fire. Allah
sent him a revelation: 'Wouldn't it have been sufficient to burn a
single ant (that bit you)?'" --Translation of Sahih Bukhari, Book 54,
Number 536
