Uefa is investigating the Real coach, who was sent off for protesting against Pepe's red card and suggested Barca are favourably treated by referees.
Thousands of images of Pepe's challenge on Daniel Alves have since appeared.
"Whoever criticises my words criticises the pictures and must think the photos and videos are altered," said Mourinho.
"An image is worth more than 1000 words and there are so many images from that game that were shown all over the world, that I have nothing else to add.
"I have nothing else to say. I have said what I wanted."
Mourinho did however go on to add that the recent events have strengthened his bond with the Spanish side.
The former Chelsea manager joined Real from Inter Milan last summer and still has four years to run on his current contract.
And despite rumours that he may depart in the summer, he stated: "To remain at Real Madrid makes more sense than ever before.
"Now I have more willingness to continue in charge of Real Madrid for what this means.
"This [Real] jersey is white, and white now has more significance."
Real and Barcelona will make formal complaints to Uefa, European football's governing body, about each other's actions during Wednesday's fiery encounter, which Barca won 2-0.
