Workflow help for Base64 image from Openai

Need workflow help with generating an image from Openai that is coming back in Base64.

I found plugin ‘Base64 File Uploader & Downloader’ to decode the base64 image (no longer URL) from Dalle. It saves the image to file manager and looks fine.

However, for the life of me I can’t work out how to get the image to attach to the Image field of the Post it was generated from. I would have thought it would be simple adding a following step “Make changes to Post’ Image = result from step 1’Url” however the Url option isnt available as seen below:

I have tried all the options and nothing works.

The Base64 plugin also has a attach_to parameter. Again I have tried every option I can think of with no success.

There are so many videos and documents about this image generation process but nothing recent with best practices with the Base64.

I am going crazy so would appreciate any help.

Note I have realised the reason it doesn’t return a URL is because I am using the gpt-image-1 model not dall-e-3 used in the video. At some point I must have seen it is cheaper to use gpt-image-1 and changed over. Gpt-image-1 does ONLY delivers in base64.

I dug a lot into this and paid someone to help but couldn’t find a way to save the base64 server side + associate to Post server side.

Let me know if you find out a way then people would be able to use the latest image model from openai.
