The image was posted over the weekend and showed workers monitoring a bank of 10 giant video screens displaying underwater images.
BP spokesperson Scott Dean, at the company's Gulf oil spill command centre in Houston, said that the two screens were blank in the original picture and a staff photographer used photoshop software to add images.
The company put the original picture up on Monday, Jul 19 after a blogger for the website Americablog wrote about the telltale incompatibilities.
Mr Dean said that the photographer was showing off his photoshop skills and there was no ill intent. He added that BP has ordered workers to use photoshop only for the things like colour correction, cropping and removing glare.
