Complaints about newspaper adverts commissioned by the Trump Organisation showing broken and rusting wind turbines under the headline 'Welcome to Scotland' have been upheld.
A picture in the Press and Journal newspaper showed the turbines, with a disclaimer admitting it was not taken in Scotland.
It was not enough to save the advert from criticism from the Advertising Standards Authority (ASA).
Donald Trump is against wind farms.
The US billionaire is campaigning to prevent the construction of a major wind farm off the Aberdeen coast, close to his new golf course at Menie.
The advert warned: "Alex Salmond wants to build 8,750 of these monstrosities".
The ASA said the pictures had given a misleading impression of the possible consequences of the Scottish government's plans to use wind turbines.
The ASA said the advert should not be used again in its current form.
