According to The Guardian:
The unnamed woman, a resident of Petrer in Alicante, south-east Spain, posted the photo on her Facebook page with the comment "Park where you bloody well please and you won't even be fined".
The police tracked her down within 48 hours and fined her.
Apparently, this is allowed in Spain so that police can "avenge their dishonor".
This is exactly the sort of behavior that leads to public distrust of police.
This story is a new take on online liberties in Spain:
A woman in Spain has been fined €800 (£570) [$886] after she took a picture of a police car parked in a disabled bay. She fell victim to a controversial new gagging law in the the country that prohibits 'the unauthorised use of images of police officers that might jeopardise their or their family's safety or that of protected facilities or police operations.'

I'd add a snarky comment here, but everything I came up with is just trolling.
Summing up my feelings: Spanish police: SRSLY, WTF?!

You're quoting the wrong document.
From the actual constitution [congreso.es] in effect in this story, article 20.1a expresses something equivalent...
...but that's modified by 20.4, which points back to article 10.1 on fundamental duties: "...respect for the law...".
So the Constitution you used is the wrong one, but the conclusion happens to turn out correctly.

Also relevant in Spain is the EU Convention on Human Rights [coe.int], which is a lot more like the US Bill of Rights than many of the European constitutions. If you're travelling to Europe, it's worth familiarizing yourself with it just in case - and obviously, Wheaton's Law still applies.
