The European Convention on Human Rights, Article 8 grants a right to privacy.
It is not clear whether or not the right under copyright law to copy an image is always sufficient to give you a right to publish the image. That depends on jurisdiction.
In the UK, for example, it does not, as a result of the way ECHR has been implemented in local law through the Human Rights Act 1998, though courts have to weigh Article 8 against Article 10 (freedom of expression) so it's not clear cut.
EDIT: The EU Data Protection Directive, and it's member state implementations (so in the UK the Data Protection Act, for example) also comes into play.
Consider e.g. that Google Street View was met with threats of lawsuits in many European countries until the blurred out faces - while Google had the right to take the pictures, and have the copyright to the images, privacy laws and human right laws in many European countries did not give them automatic right to publish those images.
