The photos were shared on the SSBN Facebook page, which is known for sharing risqué photos and clips, and quickly went viral on Wednesday night.
The photos show a man wearing jeans and a T-shirt and a woman in a maroon dress engaged in a number of "intimate" acts in what appeared to the aisle selling toilet cleaning products.
Shoppers could be seen in the background on some of the photos. Many people made negative comments on the photos.
Officers from Thailand’s Technology Crime Suppression Division (TCSD) said they are investigating the photos and are trying to track down those involved.
Pol Maj Gen Siriwat Deepai said the couple could be charged with uploading and distributing pornographic material which is punishable by up to five years in jail and a Bt100,000 fine.
