Ananke - Featured Image

Hi! I am modifying Ananke theme. Turning every post into a portfolio with ‘products_card’ from tachyons. My question is: is there any way that every post retrieves automatically their own image? I can see that Ananke defines every featured image in every .md file and i have 30 files to modify.

Thank you!!

Solved. First i transformed my posts with page bundle. Then with Resources.ByType i look for the image. So every time i create a post i just upload any image for each post and it will retrieve it automatically!
