Mothers in WA's south west are horrified that ultrasound photos of their unborn children appear to be fakes after a social media post triggered widespread alarm.

Catherine Osment paid for an ultrasound DVD and photographs of her unborn child when she attended a 4D ultrasound home business in Eaton on January 17. 

But when Mrs Osment received her photographs, she said it was "clearly obvious" all eight images were of different babies.

Scam claims ... Parents are using a Facebook page to discover that many photos have been given to multiple customers.

"I knew as soon as I opened them they were fake and it made me feel sick," Mrs Osment said.

After searching on the internet she found the same photographs in Google Images.

Mrs Osment said she took the photographs to Big W's photo centre and was told some had been printed before October last year, months before she had her scan.

Jacinta Langford, of Dalyellup, also believes an ultrasound photo of her twins was taken from Google Images.

"I'm angry and upset because I have the photo in a frame and have shared with my friends on Facebook," she said.

"Now I don't know if they are mine."

The business owner, who can not be named for legal reasons, said she was considering legal action for what she says are defamatory claims.

She told the Bunbury Mail the online comments were untrue and her work was legitimate and professional.

"I have been trained with a sonographer, not everyone can do it – it's technological stuff that the average person would not understand," she said.

"I've had a lot of phone calls of support [from previous customers]."

The issue with the pictures appeared on the Bunbury Crime Stoppers Facebook page, raising alarm among hundreds of local mothers.

Later, a ‘baby photo scam’ Facebook page was created and attracted more than 1200 members overnight.

Several mothers have compared photographs in the comments, which they believe are identical.

Stace Hart posted a photo of her scan she had nearly two years ago.

“I had this done around April 2012. And I have seen it on several posts. So upset,” she posted.

Consumer Protection spokesman Alan Hynd said the department had received several complaints about the business.

He said Consumer Protection was making inquires and anyone who was concerned should lodge a complaint at the Bunbury office.
