Open up your picture in Photofiltre and the texture you’re using. I’ll be using this texture I made.
On your texture click Ctrl+A then Ctrl+C to copy it. If you need resize your texture. I resized my texture so that the width is 500 pixels.
Now go to the picture you’re adding the texture to, in my case it’s the picture of Selena and Demi, and click Ctrl+V to paste in the texture.
Now go to Edit >> Fade Paste and set the opacity to whatever you want. I made mine 60%.
Now add just add effects. I clicked seven times.
