How to insert a image generated by DALLE into the linkedin image post

I am trying to create a scenario where I am picking up a blog post from google sheets, summarising it and using Chatgpt module to convert that into a linkedin post for my linkedin social media campaign. I am using DALLE in Chatgpt to create an image for this post. I want to insert this image in my Linkedin organisation post with image. Can someone tell me how to create this and exactly what values to put in the Linkedin module?
