Uploading files through slack

Hi, I want to know how I can upload images from slack such that when the user uploads image it could be accessed by a custom action and and produces an output image which the bot should reply to user. Can some one help me on how to achieve this?

for example: user:I want to know the damage level of the car bot: please upload an image of your damaged car user:(uploads image)image.jpg bot:(output image from a custom action)image.jpg

Thanks in advance:slightly_smiling_face:

Currently, slack doesn’t process images coming from the input message. How are you planing to process the image in custom actions to be able to answer correctly?

Did you get any solution on it ? I am looking for the same
