Many times we add one or more image attachments to a card to show the next person in our flow which images should be changed. Then when the process is done I have a butler button action like this:
move the card to the top of list "Terminado y Cumplido", add the green "Terminado y checado" label to the card, remove the yellow "Comenzado" label from the card, remove the red "No comenzado" label from the card, remove the cover image from the card, and remove link "https://trello.com"
Since the images we attach could be heavy and we have such an large amount of cards I wanted to strip the cards from any attachments
