A photographer is needed to clean up Flickr, according to the Irish Times, after it was exposed to a virus.
The paper said it had been informed by people who had been using Flickr for several months and that the photos taken by the people in question could be affected.
The Irish paper said the photos were taken of people at a beach, and it said the pictures were taken using a mobile phone.
A spokeswoman for Flickr said it was investigating.
The spokeswoman said the company was taking the incident very seriously.
